Product overview
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.
All type of the series features a high radiation hardness, in total ionizing dose (TID), in single event latch-up (SEL) and in single event upset (SEU). Housed in ceramic hermetic packages and QML-V qualified, they are ideally suited for use in the most demanding space conditions, as well as in other harsh environmental conditions.
The complete specification of each type is available from the DLA web site https://landandmaritimeapps.dla.mil/programs/smcr/default.aspx2 or directly using the hyperlinks provided in this document.
A dedicated technical note TN1181 provides additional information on the Engineering model quality level.
