File Number 4625.1
Radiation Hardened Dual-D Flip-Flop with
Set and Reset
Features
• QML Class T, Per MIL-PRF-38535
Intersil’s Satellite Applications FlowTM (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.
