ACS147MS

Radiation Hardened 10-to-4 Line Priority

Encoder

These nine-input priority encoders accept data from nine

active LOW inputs and provide a binary representation on

the four active LOW outputs. A priority is assigned to each

input so that when two or more inputs are simultaneously

active, the input with the highest priority is represented on

the output. Input line I9 has the highest priority.

These devices provide the 10-to-4-line priority encoding

function by use of the implied decimal “zero”. The “zero” is

encoded when all nine data inputs are HIGH, forcing all four

outputs HIGH.

The ACS147MS 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.

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 ACS147MS are

contained in SMD 5962-98633. A “hot-link” is provided

on our homepage for downloading.
