Intel AD68C257-250V05 is a 262,144-bit (256 Kbit) CMOS ultraviolet erasable programmable read-only memory (UVPROM) featuring a memory organization of 32K x 8 bits. This component offers a maximum access time of 250ns and operates with a nominal supply voltage of 5V. The AD68C257 series utilizes CMOS technology for low standby and maximum supply currents of 100µA and 30mA respectively. Designed for robust operation, it supports an extended temperature range from -40°C to +125°C. The device is packaged in a 28-terminal ceramic dual in-line package (CDIP28), suitable for through-hole mounting with a terminal pitch of 2.54mm. Its asynchronous operating mode and 3-state output characteristics are well-suited for applications in industrial control, telecommunications, and embedded systems where reliable, non-volatile program storage is critical.
