  • The M54HCxxx and M54HCTxxx series is composed of 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.

    They are all qualified and tested over -55°C to +125°C ambiant temperature range. The complete specification of each type is available from the ESCC web site: https://escies.org using its ESCC part number. STMicroelectronics® and guarantees full compliance of qualified parts with these ESCC specifications.
