HS-26CT31EH

Radiation Hardened Quad Differential Line Drivers

OVERVIEW

The Intersil HS-26CT31RH, HS-26CT31EH are quad differential line drivers designed for digital data transmission over balanced lines and meet 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, HS-26CT31EH accept TTL signal levels and convert them to RS-422 compatible outputs. These circuits use 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.
