54AC139数据手册ST中文资料规格书

描述 Description

The 54ACxxxx and 54ACTxxxx series are composed of 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.
