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.
