Description

The Radiation Hardened ACTS138MS is an Inverting 3-to-8 Line Decoder/Demultiplexer with three TTL level binary select inputs (A0, A1 and A2). If the device is enabled, these inputs determine which one of the eight normally high outputs will go low.

Two active low and one active high enable inputs (E1, E2 and E3) are provided to make cascaded decoder ACTS138MS designs easier to implement.

The ACTS138MS 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. These devices offer significant power reduction and faster performance when compared to ALSTTL types.
