| ACS257MS November 1997 Radiation Hardened Quad 2-Input Multiplexer with Three-State Outputs Description The Radiation Hardened ACS257MS is a Quad 2-Channel multiplexer which selects four bits of data from one of two sources under the control of a single select pin. The Output Enable input is active LOW and controls all outputs. When OE is set HIGH, all outputs are configured into a high impedance state, regardless of all other input conditions. All inputs are buffered and the outputs are designed for balanced propagation delay and transition times. The ACS257MS 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 ACS257 are contained in SMD 5962-98008.
