Differential Line Drivers
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
鹵
10V output common-mode range in TRI-STATE and 0V
output unbalance when operated with
鹵
5V supply.
Multipoint applications in differential mode with waveshaping
capacitors is not allowed.
