Absolute maximum ratings are those values beyond which the device could be permanently damaged. Absolute maximum ratings are stress ratings only and functional device operation is not implied. 2. The input and output voltage ratings may be exceeded if the input and output current ratings are observed. RECOMMENDED OPERATING CONDITIONS PARAMETER SYMBOL TEST CONDITIONS MIN TYP MAX UNIT Supply Voltage VCC 4.5 5.5 V Input Voltage VIN 0 VCC V Output Voltage VOUT 0 VCC V Operating Temperature TA -40 +85 °C Input Transition Rise or Fall Rate ∆t/∆v 500 ns ELECTRICAL CHARACTERISTICS (TA =25°C , unless otherwise specified) PARAMETER SYMBOL TEST CONDITIONS MIN TYP MAX UNIT High-level Input Voltage VIH VCC=4.5V~5.5V 2 V Low-level Input Voltage VIL VCC=4.5V~5.5V 0.8 V IOH=-20μA 4.4 4.999 V High-Level Output Voltage VOH VCC=4.5V IOH=-4mA 3.98 V IOL=20μA 0.001 0.1 V Low-Level Output Voltage VOL VCC=4.5V IOL=4mA 0.26 V Input Leakage Current II(LEAK) VCC=5.5V, VIN=VCC or GND ±0.1 μA Quiescent Supply Current ICC VCC=5.5V, VIN=VCC or GND, IOUT=0V 4 μA Additional Quiescent Supply Current Per Input Pin ∆ICC VCC=4.5V~5.5V, VIN=VCC-2.1V 1.4 2.4 mA Input Capacitance CI VCC=4.5V~5.5V, VIN=VCC or GND 3 10 pF SWITCHING CHARACTERISTICS (CL=50pF, TA =25°C , unless otherwise specified) PARAMETER SYMBOL TEST CONDITIONS MIN TYP MAX UNIT VCC=4.5V 21 35 ns Propagation delay from input ( CLR ) to output (Q or Q) tPLH / tPHL VCC=5.5V 17 31 ns VCC=4.5V 20 28 ns Propagation delay from input (CLK) to output (Q or Q) tPLH / tPHL VCC=5.5V 18 25 ns |
