It is fabricated using Operating current : 45/30mA (TYP.) very high performance, high reliability CMOS Standby current : 10 A (TYP.) LL-version technology. Its standby current is stable within the Single 2.7V ~ 5.5V power supply range of operating temperature. All inputs and outputs TTL compatible Fully static operation The LY62W102516 is well designed for low power Tri-state output application, and particularly well suited for battery Data byte control : LB (DQ0 ~ DQ7) back-up nonvolatile memory application. UB (DQ8 ~ DQ15) Data retention voltage : 1.5V (MIN.) The LY62W102516 operates from a single power Green package available supply of 2.7V ~ 5.5V and all inputs and outputs are Package : 48-pin 12mm x 20mm TSOP-I fully TTL compatible PRODUCT FAMILY Product Operating Power Dissipation Vcc Range Speed Family Temperature Standby(ISB1,TYP.)
