54AC191 Rad-Hard 4 Bit Synchronous Binary Up/Down Counter
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. ST guarantees full compliance of qualified parts with these DSCC specifications.
