M54HC74K

抗辐射型双D型触发器与预置和清除FLOP RAD HARD DUAL D TYPE FLIP FLOP WITH PRESET AND CLEAR

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.
