M54HC174:Rad-Hard Hex D-Type Flip-Flop With Clear

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.
