Texas Instruments SMJ27C256-1JM is a 262,144-bit UV erasable programmable read-only memory (UVPROM) organized as 32K words by 8 bits. This CMOS device offers asynchronous operation with a maximum access time of 170ns. It features 3-state outputs and a common I/O type. The SMJ27C256 series component is housed in a 28-lead dual in-line ceramic package (CDIP28) with through-hole mounting. Operating across a wide temperature range of -55°C to 125°C, it requires a nominal supply voltage of 5V. Typical applications include aerospace, defense, and industrial systems requiring high-reliability non-volatile storage. Screening levels are compliant with 38535Q/M, 38534H, and 883B standards.
