DATASHEET
HS-26CT32RH-T
Radiation HardenedQuad Differential Line Receiver
Intersil’s Satellite Applications Flow
TM
(SAF) devices are
fully 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.
