SK10/100EL16TA-TD
Differential Receiver
HIGH-PER.ORMANCE PRODUCTS Description
The SK10/100EL16TA-TD are differential receivers with optional input/output terminations. The EL16TA-TD family is pin-to-pin compatible with SK10/100EL16W and Motorola's MC10/100EL16 and MC10/100LVEL16, with added features of input/output terminations. The different options of input/output terminations of the EL16TA-TD make them ideal for use in high frequency design applications. It can also reduce the part count where board space is scarce. The SK10/100EL16TA has a 100 resistor across its differential inputs. The output of this device has emitter follower structure and must be terminated with 50 to -2V. This device is used in applications where the driving source has terminated outputs. Please refer to Figure 1 for more details. The SK10/100EL16TB has a 100 resistor and 8 mA current sources across its differential inputs. The latter will provide a DC path for the output currents of the driving source. The output of this device has emitter follower structure and must be terminated with 50 to -2V. This device is used in applications where the driving source may not need output termination. Please refer to Figure 2 for more details. The SK10/100EL16TC has a 100 resistor across its differential inputs and 8 mA current sources across its differential outputs. This device is used in applications where the driving source may not need output termination. Please refer to Figure 3 for more details. The SK10/100EL16TD has a 100 resistor across its differential inputs, 50 series resistance, and 8 mA current sources at its outputs. The outputs of this device may not need any termination because of the internal output 50 series resistor and current source. This device is used in applications where the driving source may not need output termination. Please refer to Figure 4 for more details. The SK10/100EL16TA-TD provides a VBB output for either single-ended use or as a DC bias for AC coupling to the device. The VBB pin should be used only as a bias for the EL16TA-TD as its current sink/source capability is limited. Whenever used, the VBB pin should be bypassed to VCC via a 0.01 F capacitor.

Notes: 1. 10EL circuits are designed to meet the DC specification shown in the table after thermal equilibrium has been established. The circuit is in a test socket or mounted on a printed circuit board, and transverse airflow greater than 500 lfpm is maintained. 2. 100K circuits are designed to meet the DC specification shown in the table where transverse airflow greater than 500 lfpm is maintained. 3. Duty cycle skew is the difference between TPLH and TPHL propagation delay through a device. 4. FMAX guaranteed for functionality only. See Figure 5 for typical output swing. VOL and VOH are guaranteed at DC only. 5. Voltages referenced to VCC = 0V. 6. Minimum input swing for which parameters are guaranteed. The device has a DC gain of ~40. 7. CMR range is referenced to the most positive side of the differential input signal. Normal operation is obtained if the high level falls within the specified range and the peak-to-peak voltage lies between VPP(min) and 1V. The lower end of the CMR range varies 1:1 with VEE and is equal to VEE + 1.7V. 8. VOP-P is obtained as follows: Voltages of Q and Q* outputs with respect to VCC are measured. The absolute difference between a high and a low state is equal to VOpp. 9. For standard ECL DC specifications, refer to the ECL Logic Family Standard DC Specifications Data Sheet. 10. For part ordering description, see HPP Part Ordering Information Data Sheet.
