Radiation Hardened Quad Differential Line Drivers

HS-26CT31RH, HS-26CT31EH

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.
