Description

The ST26C32A is a quad differential line receiver

designed to meet the RS-422, RS-423 standards

for balanced and unbalanced digital data

transmission, while retaining the low power

characteristics of CMOS.

The ST26C32A has an input sensitivity of 200mV

over the common mode input voltage range of

±7V. The ST26C32A features internal pull-up and

pull-down resistors which prevent output

oscillation on unused channels. The ST26C32A

provides an enable and disable function to all four

receivers and features 3-STATE output with 6mA

source and sink capability.
