Description
Pericom Semiconductor's PI5C series of logic circuits are produced using the Company's advanced 0.6 micron CMOS technology. The PI5C16292 and PI5C162292 are 12-bit to 24-bit Mux/Demux Bus switches designed with a low ON resistance allowing inputs to be connected directly to outputs. The PI5C162292 device has a built-in 25-ohm series resistor to reduce noise resulting from reflections, thus eliminating the need for an external terminating resistor. A2 port is not externally connected and, as a result, has an internal 500-ohm pulldown resistor to ground.
Applications
* Memory switching

Notes: 1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device. 2. Typical values are at VCC = 5.0V, TA = 25C ambient and maximum loading. 3. Not more than one output should be shorted at one time. Duration of the test should not exceed one second. 4. Measured by the voltage drop between A and B pin at indicated current through the switch. ON resistance is determined by the lower of the voltages on the two (A,B) pins. 5. This parameter is determined by device characterization but is not production tested. 2

Notes: 1. For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for applicable device. 2. Typical values are at VCC = 5.0V, +25C ambient. 3. This is the increase in supply current for S0 at the specified TTL voltage level rather than VCC or GND. 4. Per TTL driven input (VIN = 3.4V, S0 only); A and B pins do not contribute to ICC. 5. This current applies to the control inputs only and represent the current required to switch internal capacitance at the specified frequency. The A and B inputs generate no significant AC or DC currents as they transition. This parameter is not tested, but is guaranteed by design.

Notes: 1. See test circuit and waveforms. 2. This parameter is guaranteed but not tested. 3. The bus switch contributes no propagational delay other than the RC delay of the ON resistance of the switch and load capacitance. The time constant for the switch alone is of the order of 0.25ns for 50pF load. Since this time constant is much smaller than rise/fall times of typical driving signals, it adds very little propagational delay to the system. Propagational delay of the bus switch, when used in a system, is determined by the driving circuit on the driving side of the switch and its interaction with the load on the driven side. 4. Applies to tPLZ and tPZL.
