M54HC257：Rad-Hard Quad 2-Channel Multiplexer 3-State
The M54HCxxx and M54HCTxxx series are composed of 90 types of high speed CMOS functions specifically designed to meet the radiation requirements of the aerospace industry. They include a large set of gates, flip-flops, multiplexers, counters, bus interface and several other functions. The radiation hardness, the single event latch-up (SEL) immunity and the housing in hermetic packages of all types of both series make them ideally suited for use in the most difficult environmental conditions.
