Data Sheet
July 1999
File Number 4627.1
Radiation Hardened Octal D-Type
Flip-Flop, Three-State, Positive Edge
Triggered
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.
Features
• QML Class T, Per MIL-PRF-38535
• Radiation Performance

Errors/Bit-Day (Typ)
• 3 Micron Radiation Hardened SOS CMOS
The Intersil HCTS374T is a Radiation Hardened Non-
Inverting Octal D-type, Positive Edge Triggered Flip-Flop
with three-state outputs. The eight flip-flops enter data into
their registers on the LOW-to-HIGH transition of the clock
(CP). Data is also transferred to the outputs during this
transition. The output enable (OE) controls the three-state
outputs and is independent of the register operation. When
the output enable is high, the outputs are in the high
impedance state.
• Fanout (Over Temperature Range)
- Bus Driver Outputs - 15 LSTTL Loads
• Significant Power Reduction Compared to LSTTL ICs
• DC Operating Voltage Range: 4.5V to 5.5V
• LSTTL Input Compatibility
