DS26C32AT/DS26C32AM Quad Differential Line Receiver
June 1998
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
common mode input voltage range of
±
7V. The DS26C32A
features internal pull-up and pull-down resistors which pre-
vent output oscillation on unused channels.
The DS26C32A provides an enable and disable function
common to all four receivers, and features TRI-STATE
®
out-
puts with 6 mA source and sink capability. This product is pin
compatible with the DS26LS32A and the AM26LS32.
