Radiation Hardened Octal Three-State
Buffer/Line Driver
Harris’ Satellite Applications
(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 Harris ACTS541T is a Radiation Hardened Octal
Buffer/Line Driver, with three-state outputs. The output
enable pins OE1, OE2 control the three-state outputs. If
either enable is high the output will be in a high impedance
state. For data output both enables must be low.
