Radiation Hardened Octal Non-Inverting
Bidirectional Bus Transceiver
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 ACTS245T is a Radiation Hardened Octal Non-
Inverting Bidirectional Bus Transceiver intended for two-way
asynchronous communication between data busses.
