DATASHEET
HS-26C31RH-T
Radiation Hardened Quad Differential Line Driver
Intersil’s Satellite Applications Flow™ (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-26C31RH-T 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-T accepts CMOS inputs 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.
