Description

The Radiation Hardened ACS240MS is an Inverting, Octal,

Three-State Buffer/Line Driver with two active-LOW Enable

inputs (AE and BE). Each Enable input controls four outputs.

When an Enable input is LOW, the corresponding outputs

are active and input signals are inverted. A HIGH on an

Enable input causes the corresponding outputs to be high

impedance, regardless of the input levels.

The ACS240MS 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 ACS240 are

contained in SMD 5962-98540. A “hot-link” is provided

on our homepage with instructions for downloading.
