The 71256S25DB is a high-speed static RAM memory device from Quarktwin Technology Ltd., featuring a capacity of 256K bits organized as 32K x 8 bits. It offers a maximum access time of 25 ns, making it suitable for applications requiring fast data retrieval. The device operates at a supply voltage of 5V ¬± 10% and has a typical power consumption of 350 mW during active operation, with a low-power standby mode that significantly reduces power usage when not in active use. This memory chip is available in a 28-pin ceramic dual in-line package (CDIP), which allows for efficient board-level packing. It is compliant with military specifications (MIL-STD-883, Class B), ensuring high reliability and performance in demanding environments. The device also supports battery backup operation with a data retention capability at 2V, consuming only 5OºW, making it suitable for applications where power efficiency is critical. The 71256S25DB is ideal for commercial and industrial applications, with an operational temperature range of 0¬8C to 70¬8C. Its TTL-compatible input and output make it easy to integrate into existing systems. Overall, this product is a robust choice for engineers looking for reliable and efficient memory solutions in their designs.
