It is fabricated using very high performance, high reliability CMOS technology. Its standby current is stable within the range of operating temperature. The LY625128 is well designed for very low power system applications, and particularly well suited for battery back-up nonvolatile memory application. The LY625128 operates from a single power supply of 4.5V ~ 5.5V and all inputs and outputs are fully TTL compatible FEATURES Fast access time : 45/55/70ns Low power consumption: Operating current : 45/40/30mA (TYP.) Standby current : 5μA@5V(TYP.) LL/SL version 3μA@3V(TYP.)
