The Texas Instruments TMS87C257-150JE is a 32K x 8 bit UV Erasable Programmable Read-Only Memory (UVPROM) device. Featuring a maximum access time of 150ns, this CMOS component operates asynchronously and provides 3-state outputs. The memory organization is 32K words by 8 bits, offering a total density of 256 Kbits. Encased in a 28-lead Ceramic DIP (CDIP) package with a window for UV erasure, this through-hole device is suitable for applications requiring non-volatile data storage across industrial and consumer electronics sectors. It operates within a supply voltage range of 4.75V to 5.25V, with a nominal voltage of 5V, and supports an operating temperature range from -40°C to +85°C. The TMS87C257 series is designed for reliability in demanding environments.
