3 / 10 page KM68257C/CL CMOS SRAM PRELIMINARY Rev 3.0 - 3 - February-1996 ABSOLUTE MAXIMUM RATINGS* * Stresses greater than those listed under "Absolute Maximum Rating" may cause permanent damage to the device. This is a stress ra ting only and func- tional operation of the device at these at these or any other conditions above those indicated in the operating sections of thi s specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability. Parameter Symbol Rating Unit Voltage on Any Pin Relative to VSS VIN, VOUT -0.5 to 7.0 V Voltage on VCC Supply Relative to VSS VCC -0.5 to 7.0 V Power Dissipation PD 1.0 W Storage Temperature TSTG -65 to 150 °C Operating Temperature TA 0 to 70 °C RECOMMENDED DC OPERATING CONDITIONS(TA=0 to 70 °C) * VIL(Min) = -2.0(Pulse Width ≤10ns) for I≤20§Ì ** VIH(Max) = VCC+2.0V(Pulse Width ≤10ns) for I≤20§Ì Parameter Symbol Min Typ Max Unit Supply Voltage VCC 4.5 5.0 5.5 V Ground VSS 0 0 0 V Input Low Voltage VIH 2.2 - VCC+0.5** V Input Low Voltage VIL -0.5* - 0.8 V DC AND OPERATING CHARACTERISTICS(TA=0 to 70 °C,VCC=5.0V±10% unless otherwise specified) * VCC=5.0V ±5% Temp.=25°C Parameter Symbol Test Conditions Min Max Unit Input Leakage Current ILI VIN = VSS to VCC -2 2 µA Output Leakage Current ILO CS=VIH or OE=VIH or WE=VIL VOUT = VSS to VCC -2 2 µA Operating Current ICC Min.
