HS-26CT32RH-T

Radiation Hardened

Quad Differential Line Receiver

tested and guaranteed to 100kRAD total dose. These QML

Class T devices are processed to a standard flow intended

to meet the cost and shorter lead-time needs of large

volume satellite manufacturers, while maintaining a high

level of reliability.

The Intersil HS-26CT32RH-T is a Quad Differential Line

Receiver designed for digital data transmission over

balanced lines and 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-26CT32RH-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. TTL compatible Enable and Disable functions are

common to all four receivers.
