Radiation Hardened Octal Buffer/Line
Driver, Three-State
Intersil‘s Satellite Applications Flow
TM
(SAF) devices are
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 HCTS244T is a Radiation Hardened Non-
Inverting Octal Buffer/Line Driver, Three-State, with two
active-low output enables.
