DS1692/DS3692

General Description

The DS1692/DS3692 are low power Schottky TTL line driv-

ers electrically similar to the DS1691A/DS3691 but tested to

meet the requirements of MIL-STD-188-114A (see Applica-

tion Note AN-216). MIL-STD-188-114A type 1 driver specifi-

cations can be met by adding an external three resistor volt-

age divider to the output of the DS3692/1692. The DS3692/

1692 feature 4 buffered outputs with high source and sink

current capability with internal short circuit protection.

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

differential line drivers with TRI-STATE outputs. They feature

Multipoint applications in differential mode with waveshaping

capacitors is not allowed.
