Description
The HD75175 is a differential line receiver with three state outputs designed to meet the requirements of
EIA standards RS-422A, RS-423A, RS-485 and several CCITT recommendations. The device features
input sensitivity of ±200 mV over a common mode input voltage range of –12 V to +12 V. Each receiver
features two active high enables, each common to two receivers.
