HCS74T

Radiation Hardened Dual-D Flip-Flop with

Set and Reset

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.
