The Texas Instruments 5962-8769002SA is a 4Kbit (512 x 8) bipolar PROM with a parallel interface and a 40 ns access time, housed in a 20-pin ceramic flatpack. It is a non-volatile, one-time-programmable memory intended for fixed-code storage in high-reliability systems. The ceramic hermetic package protects the die from moisture and contaminants in sealed or harsh environments.
It remains in the manufacturer's current portfolio, so it is not a last-time-buy or obsolete part. For dual-sourcing or supply resilience, the AM27S25A/B3A is a pin-compatible second source with the same 512 x 8 organization, 4.5 V supply, and military temperature range, differing only in its 35 ns access time. No compliance documentation such as RoHS or REACH is carried in the record for this ceramic military-grade part.
