Quad Differential Line Receivers

General Description

Features

n High differential or common-mode input voltage ranges

The DS26LS32 and DS26LS32A are quad differential line re-

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

Standards 1020 and 1030 for balanced and unbalanced digi-

tal data transmission.

of 7V on the DS26LS32 and DS26LS32A and 15V

on the DS26LS33

0.2V sensitivity over the input voltage range on the

DS26LS32 and DS26LS32A, 0.5V sensitivity on the

DS26LS33

The DS26LS32 and DS26LS32A have an input sensitivity of

200 mV over the input voltage range of 7V and the

n DS26LS32 and DS26LS32A meet all requirements of

RS-422 and RS-423

DS26LS33 have an input sensitivity of 500 mV over the input

voltage range of 15V.

n 6k minimum input impedance

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 oscil-

lation on unused channels.

n 100 mV input hysteresis on the DS26LS32 and

DS26LS32A, 200 mV on the DS26LS33

n Operation from a single 5V supply

n TRI-STATE outputs, with choice of complementary

output enables for receiving directly onto a data bus

Each version provides an enable and disable function com-

mon to all four receivers and features TRI-STATE outputs

with 8 mA sink capability. Constructed using low power

Schottky processing, these devices are available over the

full military and commerical operating temperature ranges.
