Texas Instruments SN54S470J is a 4K x 8-bit One-Time Programmable Read-Only Memory (OTP ROM) with a maximum access time of 55ns. This TTL-compatible component features asynchronous operation and a parallel interface. The memory organization is 4K words by 8 bits, providing a total density of 32768 bits. The SN54S470 series operates across an extended temperature range from -55°C to +125°C. It is housed in a 20-pin ceramic dual in-line package (CDIP20) with through-hole mounting. Typical applications include industrial control systems, military equipment, and legacy system upgrades where non-volatile program storage is required.
