com SNLS370C – SEPTEMBER 1999 – REVISED APRIL 2013 DS78LS120/DS78LS120QML Dual Differential Line Receiver (Noise Filtering and Fail-Safe) Check for Samples: DS78LS120QML, DS78LS120 FEATURES 1 •2 Meets EIA Standards RS232-C, RS422 and RS423, Federal Standards 1020, 1030 and MIL188-114 • Input Voltage Range of ±15V (Differential or Common-mode) • Separate Strobe Input for Each Receiver • 5k Typical Input Impedance • Optional 180Ω Termination Resistor • 50mV Input Hysteresis • 200mV Input Threshold • Separate Fail-safe Mode DESCRIPTION The DS78LS120QML is a high performance, dual differential, TTL compatible line receiver 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 failsafe detection, should the input be open or short.
Each receiver includes an optional 180Ω terminating resistor and the output gate contains a logic strobe for time discrimination.
The DS78LS120QML is specified over a −55°C to +125°C temperature range.
Input specifications meet or exceed those of the popular DS7820 line receiver.
