Texas Instruments SN54S478J is a 1024 x 8-bit, TTL-compatible One-Time Programmable (OTP) Read-Only Memory (ROM). This asynchronous memory component offers a maximum access time of 30ns and operates over a temperature range of -55°C to 125°C. The SN54S478 Series device is housed in a 24-lead Ceramic Dual In-line Package (CDIP) with through-hole mounting. Its robust construction and wide operating temperature make it suitable for applications in industrial, military, and aerospace sectors requiring reliable, non-volatile data storage. The memory organization is 1K words by 8 bits, providing a total storage density of 8192 bits. Typical supply current is 140mA at a nominal supply voltage of 5V.
