Texas Instruments SN54187W is a 256 x 4-bit mask programmable read-only memory device from the SN54187 series. Featuring TTL technology, this asynchronous memory offers a maximum access time of 60ns and a total density of 1024 bits. The component is housed in a 16-lead ceramic dual in-line flat package (CDFP16) with a terminal pitch of 1.270mm. It operates across a wide temperature range of -55°C to 125°C with a nominal supply voltage of 5V and a maximum supply current of 130mA. This device is well-suited for applications requiring fixed program storage in industrial and military systems.
