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.
