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.
