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.
STMicroelectronics guarantees full compliance of
qualified parts with SMD specifications.
