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 singleevent 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.
