Description
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.
