RAD- HARD 12级二进制计数器 RAD-HARD 12 STAGE BINARY COUNTER
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.
