The HS-26C32RH-T is a quad differential line receiver designed for digital data transmission over balanced lines that meets the requirements of EIA Standard RS-422. Radiation hardened CMOS processing assures low power consumption, high speed, and reliable operation in the most severe radiation environments.

The HS-26C32RH-T has an input sensitivity of 200mV (typ.) over the common mode input voltage range of ±7V. The receivers are also equipped with input fail-safe circuitry, which causes the outputs to go to a logic "1" when the inputs are open. Enable and Disable functions are common to all four receivers.
