5962-8765003LA

The 5962-8765003LA is a high-reliability UV-erasable programmable read-only memory (EPROM) manufactured by Teledyne e2v, organized as a 16K-bit (2K x 8) non-volatile storage device. Fabricated in a 24-pin windowed CERDIP package, it belongs to the CY7C291A family and features a fast access time of 35 ns, making it suitable for legacy microprocessor systems requiring low-latency code execution. The quartz window enables complete erasure via ultraviolet light, allowing the device to be reprogrammed during development, calibration, or field maintenance cycles. Its ceramic dual-in-line package provides hermetic sealing and robust thermal performance, consistent with components built for demanding environmental conditions.

Typical applications span military avionics, defense guidance systems, and aerospace platforms where radiation tolerance and extended temperature operation are essential. The part’s 5962- prefix Standard Microcircuit Drawing designation confirms compliance with MIL-PRF-38535 or similar military specifications, often incorporating screening per MIL-STD-883 Class B or equivalent flows. Procurement considerations include the declining availability of windowed CERDIP UV EPROM technologies, as many original fabrication lines have been discontinued; this introduces obsolescence risk for long-life programs. Design sustainment teams frequently source these devices for last-time buys or life-of-type replenishment, and authentication of die revisions and traceability documentation becomes critical for high-reliability qualification.
