1. general description the nvt2003/04/06 is a family of bidirectiona l voltage level translators operational from 1.0 v to 3.6 v (v ref(a) ) and 1.8 v to 5.5 v (v ref(b) ), which allow bidirectional voltage translations between 1.0 v and 5 v without th e need for a direction pin in open-drain or push-pull applications. bit widths ranging from 3-bit to 6-bit are offere d for level translation application with transmission speeds < 33 m hz for an open-drain system with a 50 pf capacitance and a pull-up of 197 ? . when the an or bn port is low, the clamp is in the on-state and a low resistance connection exists between the an and bn ports. the low on-state resistance (r on ) of the switch allows connections to be made with minimal propagation delay. assuming the higher voltage is on the bn port when the bn po rt is high, the voltage on the an port is limited to the voltage set by vrefa. when the an port is high, the bn port is pulled to the drain pull-up supply voltage (v pu(d) ) by the pull-up resistors. this functionality allows a seamless translation between higher and lower voltages selected by the user without the need for directional control. when en is high, the translator switch is on , and the an i/o are connected to the bn i/o, respectively, allowing bidirectional data flow between ports. when en is low, the translator switch is off, and a high-impedance state exists between ports. the en input circuit is designed to be supplied by v ref(b) . to ensure the high-impedance state during power-up or power-down, en must be low. all channels have the same electrical characte ristics and there is minimal deviation from one output to another in voltage or propagat ion delay. this is a benefit over discrete transistor voltage translation solutions, since the fabrication of the s witch is symmetrical. the translator provides excellent esd protection to lower voltage devices, and at the same time protects less esd-resistant devices. 2. features and benefits ? provides bidirectional voltage translation with no direction pin ? less than 1.5 ns maximum propagation delay ? allows voltage level translation between: ? 1.0 v v ref(a) and 1.8 v, 2.5 v, 3.3 v or 5 v v ref(b) ? 1.2 v v ref(a) and 1.8 v, 2.5 v, 3.3 v or 5 v v ref(b) ? 1.8 v v ref(a) and 3.3 v or 5 v v ref(b) ? 2.5 v v ref(a) and 5 v v ref(b) ? 3.3 v v ref(a) and 5 v v ref(b) nvt2003/04/06 bidirectional voltage-level tr anslator for open-drain and push-pull applications rev. 5 ? 19 february 2014 product data sheet

). this allows vrefb to regulate the en input. a filter capacitor on vrefb is recommended. the master output driver can be totem pole or open-drain (pull-up resistors may be required) and the slave device output can be totem pole or open-drain (pull-up resistors are required to pull the bn outputs to v pu(d) ). however, if either outp ut is totem-pole, data mu st be unidirectional or the outputs must be 3-stateable and be controlled by some direction-control mechanism to prevent high-to-low contentions in either direction. if both outputs are open-drain, no direction control is needed. the reference supply voltage (v ref(a) ) is connected to the processor core power supply voltage. when vrefb is connected through a 200 k ? resistor to a 3.3 v to 5.5 v v pu(d) power supply, and v ref(a) is set between 1.0 v and (v pu(d) ? 1 v), the output of each an has a maximum output voltage equal to vrefa, and the output of each bn has a maximum output voltage equal to v pu(d) . 7.3 bidirectional level shifting be tween two different power domains nominally at the same potential the less obvious application for the nvt2003 is for level shifting between two different power domains that are nominally at the same potential, such as a 3.3 v system where the line crosses power supply domains that under normal operation would be at 3.3 v, but one could be at 3.0 v and the other at 3.6 v, or one could be experiencing a power failure while the other domain is trying to operate. one of the nvt2003 three channel transistors is used as a second reference transistor with it s b side connected to a voltage supply that is at least 1 v (and preferably 1.5 v) above the maximum possible for either v pu(a) or v pu(b) . then if either pull-up voltage is at 0 v, the channels are disabled, and otherwise the channels are biased such that they turn off at the lower pull-up voltage, and if the two pull-up voltages are equal, the channel is biased such that it just turns off at the common pull-up voltage. nvt2003_04_06 all information provided in this document is subject to legal disclaimers. ?

the driver sink current ? the v ol of driver ? the v il of the driver ? frequency of operation the following tables can be used to estimate the pull-up resistor value in different use cases so that the minimum resistance for the pull-up resistor can be found. ta b l e 6 , ta b l e 7 and table 8 contain suggested minimum values of pull-up resistors for the pca9306 and nvt20xx devices with typical voltage translation levels and drive currents. the calculated values assume that both drive currents are the same. v ol =v il =0.1 ? v cc and accounts for a ? 5%v cc tolerance of the supplies, ? 1% resistor values. it should be noted that the re sistor chosen in the final application should be equal to or larger than the values shown in ta b l e 6 , table 7 and ta b l e 8 to ensure that the pass voltage is less than 10 % of the v cc voltage, and the external driver should be able to sink the total current from both pull-up resistors. when selecting the minimum resistor value in ta b l e 6 , ta b l e 7 or table 8 , the drive current strength that should be chosen should be the lowest drive current seen in the application and account for any drive strength current scaling with output vo ltage. for the gtl devices, the resistance table should be recalculated to account for the difference in on resistance and bias voltage limitations between v cc(b) and v cc(a) . the applied enable voltage v pu(h) and the applied voltage at v ref(a) and v ref(b) should be such that v ref(h) is at least 1 v higher than v ref(a) and v ref(b) for best translator operation. fig 10. bidirectional level shifting between two different power domains 002aae967 a1 a2 vrefa gnd 3 4 vrefb 1 8 7 b1 b2 10 en sw sw nvt2003 9 200 k r pu r pu v pu(b) = 3.3 v i 2 c-bus device scl sda v cc gnd 2 v pu(a) = 3.3 v r pu r pu i 2 c-bus master scl sda v cc gnd v pu(h) a3 5 6 sw b3 v pu(b) nvt2003_04_06 all information provided in this document is subject to legal disclaimers. ?

(1) the rise and fall times are dependent upon translation voltages, the drive strength, the total node capacitance (c l(tot) ) and the pull-up resistors (r pu ) that are present on the bus. the node capacitance is the addition of the pcb trace capacitance and the device capacitance that exists on the bus. beca use of the dependency of the external components, pcb layout and the different devic e operating states the calculation of rise and fall times is complex and has several inflection points along the curve. the main component of the rise and fall times is the rc time constant of the bus line when the device is in its two primary operating stat es: when device is in the on state and it is low-impedance, the other is when the device is off isolating the a-side from the b-side. a description of the fall time applied to either an or bn output going from high to low is as follows. whichever side is asserted first, the b-side down must discharge to the v cc(a) voltage. the time is determined by the pull-up resistor, pull-down driver strength and the table 8. pull-up resistor minimum values, 15 ma driver sink current for pca9306 and nvt20xx a-side b-side 1.2 v 1.5 v 1.8 v 2.5 v 3.3 v 5.0 v 1.0 v r pu(a) = 147 ? r pu(b) = 147 ? r pu(a) =169 ? r pu(b) =169 ? r pu(a) = 191 ? r pu(b) = 191 ? r pu(a) = none r pu(b) =178 ? r pu(a) = none r pu(b) = 237 ? r pu(a) = none r pu(b) =365 ? 1.2 v r pu(a) =182 ? r pu(b) =182 ? r pu(a) = 205 ? r pu(b) = 205 ? r pu(a) = none r pu(b) =178 ? r pu(a) = none r pu(b) = 237 ? r pu(a) = none r pu(b) =365 ? 1.5 v r pu(a) = 221 ? r pu(b) = 221 ? r pu(a) = none r pu(b) =174 ? r pu(a) = none r pu(b) = 232 ? r pu(a) = none r pu(b) =357 ? 1.8 v r pu(a) =294 ? r pu(b) =294 ? r pu(a) = none r pu(b) = 232 ? r pu(a) = none r pu(b) =357 ? 2.5 v r pu(a) = 392 ? r pu(b) = 392 ? r pu(a) = none r pu(b) =357 ? 3.3 v r pu(a) = none r pu(b) =348 ? fig 11. an example waveform for maximum frequency f max 1 t low min ?? t high min ?? t r actual ?? t f actual ?? +++ ------------------------------------------------------------------------------------------------------------ - = 002aag912 t r(actual) t f(actual) gnd v ol v il v ih v cc t high(min) t low(min) 1 / f max 0.9 v cc 0.1 v cc nvt2003_04_06 all information provided in this document is subject to legal disclaimers. ? nxp b.v. 2014. all rights reserved. product data sheet rev. 5 ? 19 february 2014 12 of 33 nxp semiconductors nvt2003/04/06 bidirectional voltage-level translator capacitance. as the le vel moves below the v cc(a) voltage, the channel resistance drops so that both a and b sides equal. the capacita nce on both sides is connected to form the total capacitance and the pull-up resistors on both sides combine to the parallel equivalent resistance. the r on of the device is small compared to the pull-up resistor values, so its effect on the pull-up resistance can be neglected and the fall is determined by the driver pulling the combined capacitance and pull-up resi stor currents. an estimation of the actual fall time seen by the device is equal to the time it takes fo r the b-side to fall to the v cc(a) voltage and the time it takes for both sides to fall from the v cc(a) voltage to the v il level. a description of the rise time applied to either an or bn output going from low to high is as follows. when the signa l level is low, the r on is at its minimum, so the a and b sides are essentially one node . they will rise together with an rc time constant that is the sum of all the capacitance from both sides and the parallel of the resistance from both sides. as the signal approaches the v cc(a) voltage, the channel resistance goes up and the waveforms separate, with the b side finishing its rise with the rc time constant of the b side. the rise to v cc(a) is essentially the same for both sides. there are some basic gu idelines to follow that will help ma ximize the performance of the device: ? keep trace length to a minimum by placin g the nvt device clos e to the processor. ? the signal round trip time on trace should be shorter than the rise or fall time of signal to reduce reflections. ? the faster the edge of the signal, the higher the chance for ringing. ? the higher drive strength controlled by the pull-up resistor (up to 15 ma), the higher the frequency the device can use. the system designer must design the pull-up resistor value based on external current drive strength and limit the node capacita nce (minimize the wire, stub, connector and trace length) to get the desired operation frequency result. 8. limiting values [1] the input and input/output negative voltage ratings may be exceeded if the input and input/output clamp current ratings are observed.
