ACTS138MS Radiation Hardened TTL Input, 3-to-8 Line Decoder/Demultiplexer December 1997 Features Description • QML Qualified Per MIL-PRF-38535 Requirements 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. • 1.25Micron Radiation Hardened SOS CMOS • Radiation Environment - Latch-up Free Under any Conditions - Total Dose . . . . . . . . . . . . . . . . . . . . . . 3 x 105 RAD(Si) - SEU Immunity . . . . . . . . . . . <1 x 10-10 Errors/Bit/Day - SEU LET Threshold . . . . . . . . . . . >100MeV/(mg/cm2) Two active low and one active high enable inputs (E1, E2 and E3) are provided to make cascaded decoder designs easier to implement. • Input Logic Levels . . . . . . . . . . VIL = 0.8V, VIH = (Vcc/2) 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. • Output Current . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ±12mA • Quiescent Supply Current. . . . . . . . . . . . . . . . . . . .20µA • Propagation Delay . . . . . . . . . . . . . . . . . . . . . . . . . . 20ns Applications Specifications for Rad Hard QML devices are controlled by the Defense Supply Center in Columbus (DSCC).
