Description

The Radiation Hardened ACS253MS is a Dual 4-Channel Mul-

tiplexer having two common binary control inputs for selecting 1

of 4 data channels. All inputs and outputs are buffered and are

designed for balanced propagation delay and transition times.

Separate Output Enable inputs are provided to ease system

design. When OE1 or OE2 are set HIGH, the corresponding

output is configured into a high impedance state.

The ACS253MS 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.

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 ACS253 are

contained in SMD 5962-98007. A “hot-link” is provided

on our homepage with instructions for downloading.
