DS26C32AT/DS26C32AM

Quad Differential Line Receiver

General Description

The DS26C32A is a quad differential line receiver designed

to meet the RS-422, RS-423, and Federal Standards 1020

and 1030 for balanced and unbalanced digital data transmis-

sion, while retaining the low power characteristics of CMOS.

The DS26C32A has an input sensitivity of 200 mV over the

features internal pull-up and pull-down resistors which pre-

vent output oscillation on unused channels.

The DS26C32A provides an enable and disable function

outputs with 6 mA source and sink capability. This product is

pin compatible with the DS26LS32A and the AM26LS32.
