HCS244T

Radiation Hardened Octal Buffer/Line

Driver, Three-State

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 Non-

Inverting Octal Buffer/Line Driver, Three-State, with two

active-low output enables.
