ACS139MS
November 1997
Radiation Hardened
Dual 2-to-4 Line Decoder/Demultiplexer
Description
The Radiation Hardened ACS139MS contains two indepen-
dent binary to one-of-four decoders, each with a single active
low enable input. Data on the select inputs cause one of the
four normally high outputs to go low.
If the enable input is high, all four outputs remain high. During
demultiplexer operation the enable input acts as the data input.
The enable input also functions as a chip select when the
devices are cascaded.
The ACS139MS 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 ACS139 are
contained in SMD 5962-97639. A 鈥渉ot-link鈥?is provided
on our homepage with instructions for downloading.
