This document describes the features and characteristics of the M54HCxxx and M54HCTxxx series products. These products are high speed CMOS functions specifically designed to meet the radiation requirements of the aerospace industry. They have radiation hardness, single event latch-up (SEL) immunity, and are housed in hermetic packages, making them ideally suited for use in the most difficult environmental conditions.
The document describes the M54HCxxx and M54HCTxxx series, which consist of over 90 types of high-speed CMOS functions designed specifically to meet radiation requirements in the aerospace industry. The series includes various gates, flip-flops, multiplexers, counters, and bus interface components.
