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 transmission, while retaining

the low power characteristics of CMOS.

The DS26C32A has an input sensitivity of 200 mV

over the common mode input voltage range of ±7V.

The DS26C32A features internal pull-up and pull?

down resistors which prevent output oscillation on

unused channels.

The DS26C32A provides an enable and disable

function common to all four receivers, and features

TRI-STATE outputs with 6 mA source and sink

capability. This product is pin compatible with the

DS26LS32A and the AM26LS32.
