Intersil Corporation HCS244T Datasheet
HCS244T
Data Sheet July 1999 File Number
Radiation Hardened Octal Buffer/Line
Driver, Three-State
Intersil‘s Satellite Applications FlowTM (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 HCS244T is a Radiation Hardened NonInverting Octal Buffer/Line Driver, Three-State, with two
active-low output enables.
Specifications
Specifications for Rad Hard QML devices are controlled by
the Defense Supply Center in Columbus (DSCC). The SMD
numbers listed below must be used when ordering.
Detailed Electrical Specifications for the HCS244T are
contained in SMD 5962-95731. A “hot-link” is provided from
our website for downloading.
