DS1692/DS3692
TRI-STATE
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
10V output common-mode range in TRI-STATE and 0V
output unbalance when operated with
5V supply.
Multipoint applications in differential mode with waveshaping
capacitors is not allowed.

Note 2: "Absolute Maximum Ratings" are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the devices
should be operated at these limits. The table of "Electrical Characteristics" provide conditions for actual device operation.
Note 3: Unless otherwise specified, min/max limits apply across the -55C to +125C temperature range for the DS1692 and across the 0C to +70C range for the
DS3692. All typicals are given for V

as listed in operating conditions.
Note 4: All currents into device pins are positive; all currents out of device pins are negative. All voltages are referenced to ground unless otherwise specified.
Note 5: Only one output at a time should be shorted.
