Texas Instruments SN74187J is a 1024-bit (256 words x 4 bits) asynchronous mask read-only memory organized as 256 words by 4 bits. This TTL-compatible device features a maximum access time of 60ns, suitable for applications requiring fixed, non-volatile data storage. The SN74187 series component is housed in a 16-pin ceramic dual in-line package (CDIP16), designed for through-hole mounting. Its typical operating voltage is 5V, with a maximum supply current of 130mA. This memory component finds application in various industrial and consumer electronics, including control systems and legacy equipment where static program or data storage is critical. The SN74187J operates within a temperature range of 0°C to 70°C.
