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).
