HS-26CT31RH

Radiation Hardened Quad Differential Line

Driver

The Intersil HS-26CT31RH 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 accepts TTL 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

Specifications for Rad Hard QML devices are controlled by
