The 71256S45DB is a 256K-bit (32K x 8-bit) high-speed static RAM produced by Quarktwin Technology Ltd. It features a maximum access time of 45 ns and operates with a supply voltage of 5V ¬± 10%. This memory device is designed for low-power operation, consuming approximately 350 mW during active use and only 5 OºW in battery backup mode, which allows for data retention at 2V. The device is available in a 28-pin ceramic DIP package, suitable for high-density board layouts. The 71256S45DB is compliant with military standards (MIL-STD-883, Class B), making it suitable for applications requiring high reliability and performance in harsh environments. It operates over an industrial temperature range of -40¬8C to +85¬8C, ensuring functionality in various conditions. The memory is TTL-compatible for both input and output, facilitating integration into existing systems. This product is ideal for engineers seeking a reliable and efficient memory solution for military or industrial applications.
