Radiation Hardened Quad Differential Line
Driver
The Intersil HS-26C31RH is a quad differential line driver
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-26C31RH accepts CMOS signal levels and converts
them to RS-422 compatible outputs. This circuit uses special
outputs that enable the drivers to power down without loading
down the bus. Enable and disable pins allow several devices to
be connected to the same data source and addressed
independently.
Specifications for Rad Hard QML devices are controlled
by the Defense Supply Center in Columbus (DSCC). The
SMD numbers listed here must be used when ordering.
Detailed Electrical Specifications for these devices are
contained in SMD 5962-96663. A “hot-link” is provided
on our homepage for downloading.
