Description

The Intersil HCS139MS 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.

If the enable input is high all four outputs remain high. For

demultiplexer operation the enable input is the data input.

The enable input also functions as a chip select when these

devices are cascaded.

The HCS139MS utilizes advanced CMOS/SOS technology

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

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

The HCS139MS is supplied in a 16 lead Ceramic flatpack

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