The Texas Instruments TMS87C257JE is a 262,144-bit (32K x 8) CMOS UV EPROM with a maximum access time of 250ns. This asynchronous memory device features common I/O and 3-state outputs, operating from a 4.75V to 5.25V supply. Packaged in a 28-lead Dual In-line Package (DIP) with a ceramic, glass-sealed body and a window for UV erasure, it is designed for through-hole mounting. The TMS87C257 series is utilized in applications requiring non-volatile program storage, including embedded systems and industrial control equipment. Operating temperature ranges from -40°C to +85°C. Standby current is rated at 250µA maximum, with a supply current of 30mA maximum.
