ACS14MS

Radiation Hardened Hex Inverting Schmitt Trigger

DATASHEET

The Radiation Hardened ACS14MS is a Hex Inverting

Schmitt Trigger. This device simply inverts the level present

on each input. The Schmitt Trigger input stage provides

400mV (Min) of hysteresis and permits input signals with

longer rise times. All inputs are buffered and the outputs are

designed for balanced propagation delay and transition

times.

The ACS14MS 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 ACS14MS are

contained in SMD 5962-98623.
