ACS253MS
November 1997
Radiation Hardened
Dual 4-Input Multiplexer with Three-State Outputs
Description
The Radiation Hardened ACS253MS is a Dual 4-Channel Mul-
tiplexer having two common binary control inputs for selecting 1
of 4 data channels. All inputs and outputs are buffered and are
designed for balanced propagation delay and transition times.
Separate Output Enable inputs are provided to ease system
design. When OE1 or OE2 are set HIGH, the corresponding
output is con鏗乬ured into a high impedance state.
The ACS253MS 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 signi鏗乧ant
power reduction and faster performance when compared to
ALSTTL types.
Speci鏗乧ations 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 Speci鏗乧ations for the ACS253 are
contained in SMD 5962-98007. A 鈥渉ot-link鈥?is provided
on our homepage with instructions for downloading.
