54ACxxxx, 54ACTxxxx Rad-hard advanced high-speed 5 V CMOS logic series Data brief Features AC: 2 to 6 V operating voltage ACT: 4.5 to 5.5 V operating voltage High speed T = 4.5 ns (typ.) PD Low DC power dissipation: 8 A max. Symmetrical 24 mA output characteristics Flat-14 DIL-14 High noise immunity: 28% of min. V CC Power-down input protection Balanced propagation delays Improved electrical latch-up immunity Controlled rise and fall times Operating temperature: - 55 to 150 C Flat-16 DIL-16 Hermetic packages Rad-hard: 300 kRad TID at any Mil1019 dose rates SEL immune to 110 MeV/cm/mg LET ions RHA QML-V qualified Same die and electrical specification for engineering and flight models Flat-20 DIL-20 Description The 54AC and 54ACT series represent over 60 product types with different 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 interfaces, and several other functions. Their radiation hardness, immunity from single event latch-up (SEL) and single event upset (SEU), and housing in Flat-48 hermetic packages make them suitable for the most difficult environmental conditions. The The upper metallic lid is not electrically connected to any complete specification for each type is available pins, nor to the IC die inside the package. from the DSCC web site: www.dscc.dla.mil.
