Rad-hard high voltage CMOS logic series
Description
The HCC40xxx and HCC45xxx series are composed of over 70 types of high voltage CMOS
functions, offering a set of highly noise tolerant gates, Flip-Flops, multiplexers, counters, bus
interfaces and several other functions. The radiation hardness, the single event latch-up
(SEL) and the single event upset (SEU) immunity and the housing in hermetic packages of all types
of both series make them usable in the most difficult environmental conditions.
