• Industrial control units requiring wide temperature operation

Memory IC Procurement Notes

This component is classified as obsolete and discontinued by the manufacturer. Availability is restricted to existing stock held by authorized distributors or surplus suppliers. Verification of part authenticity and physical condition is critical due to the end-of-life status. Buyers must confirm specific lot dates and ensure compliance with export control regulations applicable to military-grade hardware before finalizing any acquisition.

Memory IC Selection Notes

Engineers selecting this part should prioritize its military qualification and wide thermal range over commercial alternatives. The 20 ns access speed defines its performance ceiling for synchronous system integration. Designers must account for the CDIP-28 through-hole footprint during PCB layout. The single 5V supply requirement simplifies power rail design but necessitates careful consideration of the battery backup circuitry to maintain data integrity during power transitions.
