The 7142SA55J is a high-speed 2K x 8 Dual-Port Static RAM from Quarktwin Technology Ltd., designed for asynchronous access with a maximum access time of 55 ns. It operates on a single 5V ±10% power supply and features low power consumption, typically drawing 325mW during active operation and 5mW in standby mode. This memory device supports independent access for reads and writes, making it suitable for applications requiring simultaneous data access. The 7142SA55J is available in multiple package types, including 48-pin DIP, LCC, and PLCC, and is compliant with military specifications, ensuring reliability in demanding environments. Additionally, it offers battery backup operation with 2V data retention capability in low-power versions. The device is ideal for systems that require dual-port memory solutions without the need for additional discrete logic.
