ACS139MS
Radiation Hardened
Dual 2-to-4 Line Decoder/Demultiplexer
November 1997
Features
Description
• QML Qualified Per MIL-PRF-38535 Requirements
• 1.25Micron Radiation Hardened SOS CMOS
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.
• Radiation Environment
- Latch-up Free Under any Conditions
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 significant
power reduction and faster performance when compared to
ALSTTL types.
