DS1692/DS3692 TRI-STATE® Differential Line Drivers<br />

General Description<br />

The DS1692/DS3692 are low power Schottky TTL line drivers<br />

electrically similar to the DS1691A/DS3691 but tested<br />

to meet the requirements of MIL-STD-1 88-114 (see Application<br />

Note AN-216). They feature 4 buffered outputs with<br />

high source and sink current capability with internal short<br />

circuit protection. A mode control input provides a choice of<br />

operation either as 4 independent line drivers or 2 differential<br />

line drivers. A rise time control pin allows the use of an<br />

external capacitor to reduce rise lime for suppression of<br />

near end cross-talk to other receivers in the cable.<br />

With the mode select pin low, the DS1692/DS3692 are dual<br />

differential line drivers with TRI-STATE outputs. They feature<br />

± 10V output common-mode range in TRI-STATE and<br />

OV output unbalance when operated with ± 5V supply.<br />

Features<br />

• Dual differential line driver or quad single-ended line<br />

driver<br />

• TRI-STATE differential drivers meet MIL-STD-188-114<br />

• Short circuit protection for both source and sink outputs<br />

• Individual rise time control for each output<br />

• 1000 transmission line drive capability<br />

• Low Icc and lEE power consumption<br />

Differential mode<br />

Single-ended mode<br />

26 mW/drivertyp<br />

• Low current PNP inputs compatible with TIL, MOS and<br />

CMOS<br />
