ACS157MS
Radiation Hardened
Quad 2-Input Non-Inverting Multiplexer
December 1997
Features
Description
• QML Qualified Per MIL-PRF-38535 Requirements
• 1.25Micron Radiation Hardened SOS CMOS
The Radiation Hardened ACS157MS is a Quad 2-Channel
Non-Inverting Multiplexer which selects four bits of data from
one of two sources under the control of a single Select pin.
The Output Enable input is active LOW and controls all out-
puts. When E is set HIGH, all outputs are forced LOW,
regardless of all other input conditions. All inputs are buff-
ered and the outputs are designed for balanced propagation
delay and transition times.

The ACS157MS is fabricated on a CMOS Silicon on Sap-
phire (SOS) process, which provides an immunity to Single
Event Latch-up and the capability of highly reliable perfor-
mance in any radiation environment. These devices offer
significant power reduction and faster performance when
compared to ALSTTL types.
