M54HCxxx, M54HCTxxx Datasheet Rad-hard high speed 2 to 6 V CMOS logic series Flat-14 Flat-16 DIL-14 DIL-16 Flat-24 DIL-24 The upper metallic lid is not electrically connected to any pins, nor to the IC die inside the package Product status link M54HCxxx, M54HCTxxx Features • ESCC qualified • 7 V Absolute maximum ratings • 2 V to 6 V operating voltage for CMOS M54HCxxx series • 4.5 V to 5.5 V operating voltage for TTL M54HCTxxx series • Hermetic packages • Rad-hard 50 krad (Si) TID • SEL immune up to 110 MeV.cm²/mg • -55 °C to +125 °C temperature range • ESCC specification available on ESCC website for each part Description 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.
