Description

The Intersil HCTS139MS is a Radiation Hardened 2-to-4 line

Decoder/Demultiplexer with an active low enable (E). Data

on the select inputs (A0, A1) cause one of the four normally

high outputs to go to a low logic level. The Demultiplexing

function is performed by using the enable input as the data

input.

The HCTS139MS utilizes advanced CMOS/SOS technology

to achieve high-speed operation. This device is a member of

radiation hardened, high-speed, CMOS/SOS Logic Family

with TTL input compatibility.

The HCTS139MS is supplied in a 16 lead Ceramic flatpack

(K suffix) or a SBDIP Package (D suffix).
