DS34C86T
Quad CMOS Differential Line Receiver
General 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 transmis-
sion, 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
vided to improve noise margin and discourage output insta-
bility for slowly changing input waveforms.
The DS34C86T features internal pull-up and pull-down resis-
tors which prevent output oscillation on unused channels.
Separate enable pins allow independent control of receiver
pairs. The TRI-STATE
capability. The DS34C86T is pin compatible with the
DS3486.
