Radiation Hardened Dual-D Flip-Flop with
Set and Reset
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 HCS74T is a Radiation Hardened Positive Edge
Triggered Flip-Flop with set and reset.
The HCS74T utilizes advanced CMOS/SOS technology to
achieve high-speed operation. This device is a member of
radiation hardened, high-speed, CMOS/SOS Logic Family.
