ACS138MS FN4461
Rev.0.00
December 1997 Radiation Hardened 3-to-8 Line Decoder/Demultiplexer Features Description QML Qualified Per MIL-PRF-38535 Requirements The Radiation Hardened ACS138MS is an Inverting 3-to-8
Line Decoder/Demultiplexer with three binary select inputs
(A0, A1 and A2). If the device is enabled, these inputs determine which one of the eight normally high outputs will go
low. 1.25Micron Radiation Hardened SOS CMOS Radiation Environment

and E3) are provided to make cascaded decoder designs
easier to implement.
The ACS138MS 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.
