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
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.
