Rad-Hard Dual D-Type Flip-Flop With Preset & Clear

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 hermetic packages make them suitable for the most difficult environmental conditions. The complete specification for each type is available from the DSCC web site: www.dscc.dla.mil. STMicroelectronics guarantees full compliance of qualified parts with these DSCC specifications.
