HS-26CT31RH-T
Data Sheet
July 1999
File Number
4590.1
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-26CT31RH-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-26CT31RH-T accepts TTL 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.
