Description

The M54HCxxx and M54HCTxxx series are composed of over 90 types of high speed CMOS functions specifically designed to meet the radiation requirements of the aerospace industry. It includes 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.
