Intersil Corporation HS-26CT31RH-T Datasheet
HS-26CT31RH-T
Data Sheet July 1999 File Number
Radiation Hardened
Quad Differential Line Driver
Intersil’sSatellite Applications Flow™(SAF) devicesare 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 ov er 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 sev ere radiation
environments.
TheHS-26CT31RH-T accepts TTLinputs and convertsthem to
RS-422 compatible outputs. This circuit uses special outputs
that enable the drivers to powerdown without loading down the
bus. Enable and disab le pins allowseveral de vices to be
connected to the same data source and addressed
independently.
Specifications
Specifications for Rad Hard QML devices are controlled by
