DESCRIPTION

The DS34C86T 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 DS34C86T has an input sensitivity of 200 mV

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

Hysteresis is provided to improve noise margin and

discourage output instability for slowly changing input

waveforms.

The DS34C86T features internal pull-up and pulldown

resistors which prevent output oscillation on

unused channels.

Separate enable pins allow independent control of

receiver pairs. The TRI-STATE outputs have 6 mA

source and sink capability. The DS34C86T is pin

compatible with the DS3486.
