HCC4042B：Rad-hard quad clocked D latch

The HCC40xxx and HCC45xxx series are composed of 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, single event latch-up (SEL), 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.

The complete specification of each type is available from the European Space Components Coordination (ESCC) web site: https://spacecomponents.org/. ST guarantees full compliance of qualified parts with these ESCC detailed specifications.
