Description

The Radiation Hardened ACS138MS is an Inverting 3-to-8 Line Decoder/Demultiplexer with three 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 designs easier to implement. The ACS138MS 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. Specifications for Rad Hard QML devices are controlled by the Defense Supply Center in Columbus (DSCC). The SMD numbers listed below must be used when ordering. Detailed Electrical Specifications for the ACS138MS are contained in SMD 5962-98534. A hot-link is provided on our homepage with instructions for downloading. http://www.intersil.com/data/sm/index.htm
