Radiation Hardened Hex D-Type Flip-Flop
with Reset
Features
• QML Qualified Per MIL-PRF-38535 Requirements
• 1.25 Micron Radiation Hardened SOS CMOS
The Radiation Hardened ACS174MS is a Hex D-Type Flip-
Flop with Reset. Information at the D input is transferred to
the Q output on the positive-going transition of the clock. All
six flip-flops are controlled by a common clock (CP) and a
common reset (MR). Resetting is accomplished by a LOW
level independent of the clock. All inputs are buffered and
the outputs are designed for balanced propagation delay
and transition times.

The ACS174MS is fabricated on a CMOS Silicon on
Sapphire (SOS) process, which provides an immunity to
Single Event Latch-up and the capability of highly reliable
performance in any radiation environment. These devices
offer significant power reduction and faster performance
when compared to ALSTTL types.
