DS26C32AT/DS26C32AM
Quad Differential Line Receiver
General Description
Features
n CMOS design for low power
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.
±
n
0.2V sensitivity over input common mode voltage
range
n Typical propagation delays: 19 ns
n Typical input hysteresis: 60 mV
The DS26C32A has an input sensitivity of 200 mV over the
±
common mode input voltage range of 7V. The DS26C32A
=
n Inputs won’t load line when VCC 0V
features internal pull-up and pull-down resistors which pre-
vent output oscillation on unused channels.
n Meets the requirements of EIA standard RS-422
n TRI-STATE outputs for connection to system buses
n Available in Surface Mount
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.

CMOS 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 to 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. Each receiver is also equipped with input fail-safe circuitry, which causes the
output to go to a logic "1" state when the inputs are open.
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.
