Description

The DS78LS120 and DS88LS120 are high performance,
dual differential, TTL compatible line receivers for both balanced
and unbalanced digital data transmission. The inputs
are compatible with EIA, Federal and MIL standards.
The line receiver will discriminate a ±200 mV input signal over a common-mode range of ±10V and a ±300 mV signal over a range of ±15V.

Circuit features include hysteresis and response control for applications where controlled rise and fall times and/or high frequency noise rejection are desirable. Threshold offset control is provided for fail-safe detection, should the input be open or short. Each receiver includes an optional 180W terminating resistor and the output gate contains a logic strobe for time discrimination. The DS78LS120 is specified over a −55°C to +125°C temperature range and the DS88LS120  from 0°C to +70°C. Input specifications meet or exceed those of the popular DS7820/DS8820 line receiver.
