Description

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.

Specifications 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 Specifications for the ACS157 are

contained in SMD 5962-98536. A “hot-link” is provided

on our homepage with instructions for downloading.
