ACS175MS
Radiation Hardened Quad D-Type Flip-
Flop with Reset
The Radiation Hardened ACS175MS is a Quad D-Type
Flip-Flop with Reset. Information at the D input is
transferred to the Q and
Q outputs on the positive-going
transition of the clock. All four 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 ACS175MS 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.
Specifications for Rad Hard QML devices are controlled
by the Defense Supply Center in Columbus (DSCC). The
SMD numbers listed below must be used when ordering.
Detailed Electrical Specifications for the ACS175MS are
contained in SMD 5962-98635. A “hot-link” is provided
on our homepage for downloading.
