ACS139MS - Radiation Hardened Dual 2-to-4 Line Decoder/Demultiplexer

General Description

The Radiation Hardened ACS139MS contains two independent binary to one-of-four decoders, each with a single active low enable input.

Data on the select inputs cause one of the four normally high outputs to go low.

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

ACS139MS November 1997 Radiation Hardened Dual 2-to-4 Line Decoder/Demultiplexer Description The Radiation Hardened ACS139MS contains two independent binary to one-of-four decoders, each with a single active low enable input. Data on the select inputs cause one of the four normally high outputs to go low. If the enable input is high, all four outputs remain high. During demultiplexer operation the enable input acts as the data input. The enable input also functions as a chip select when the devices are cascaded. The ACS139MS 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.
