DS26LS32MQML

Quad Differential Line Receivers

General Description

The DS26LS32 and DS26LS32A are quad differential line

receivers designed to meet the RS-422, RS-423 and Federal

Standards 1020 and 1030 for balanced and unbalanced

digital data transmission.

The DS26LS32 and DS26LS32A have an input sensitivity of

DS26LS33 have an input sensitivity of 500 mV over the input

The DS26LS32A differ in function from the popular

DS26LS32 and DS26LS33 in that input pull-up and pull-

down resistors are included which prevent output oscillation

on unused channels.

Each version provides an enable and disable function com-

with 8 mA sink capability. Constructed using low power

Schottky processing, these devices are available over the

full military and commerical operating temperature ranges.
