The M54HCxxx and M54HCTxxx series comprises CMOS functions tailored to meet aerospace radiation demands. They encompass a vast array of gates, flip-flops, multiplexers, counters, bus interfaces, and more. The HC/HCT series' maximum operating frequency ranges from 20 to 55 MHz at 4.5 V and 25 °C, varying by product. All series types exhibit total dose hardness at 50 krad(Si), high single event latch-up (SEL) immunity, and a wide operating temperature range. Encased in ceramic hermetic packages, all series products are ESCC qualified, ideal for space and harsh environments. Detailed specifications for each type are available on the ESCC website using its ESCC part number.
