  • The M54HCxxx and M54HCTxxx series are composed of 90 types of high speed 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.

    Key Features

    • 2 to 6 V operating voltage
    • Low power DC dissipation: 1 μA max. at 25 °C
    • High speed tPD = 8 ns typ. at 25 °C
    • Symmetrical outputs characteristics
    • High noise immunity: 28 % of min. VCC
    • Hermetic packages
    • Rad-hard 50 krad (Si)
    • SEL immune up to 110 MeV/mg/cm²
    • ESCC qualified
    • Same die and electrical specification for engineering and flight models
    • The complete specification of each type is available from the ESCC web site: https://escies.org using its ESCC part number. STMicroelectronics®guarantees full compliance of qualified parts with these ESCC specifications.
