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 (TA=25°C, unless otherwise specified) PARAMETER SYMBOL CONDITIONS MIN Supply Voltage VCC 4.5 Input Voltage VIN 0 Output Voltage VOUT 0 Input Transition Rise or Fall Rate t/v VCC=5.0+0.5V Operating Temperature TA -40  STATIC CHARACTERISTICS (TA=25°C, unless otherwise specified) TYP MAX 5.5 5.5 VCC 20 +125 UNIT V V V ns/V °C PARAMETER High-Level Input Voltage Low-Level Input Voltage High-Level Output Voltage Low-Level Output Voltage Input Leakage Current Quiescent Supply Current Additional quiescent Supply Current Input Capacitance SYMBOL VIH VIL VOH VOL II(LEAK) IQ IQ CIN TEST CONDITIONS VCC = 4.5~5.5 V VCC = 4.5~5.5 V VCC = 4.5V, IOH = -50 μA VCC = 4.5V, IOH = -8 mA VCC = 4.5V, IOL = 50μA VCC = 4.5V, IOL = 8 mA VCC = 5.5V, VIN = VCC or GND VCC = 5.5V, VIN = VCC or GND, IOUT = 0 VCC = 5.5V, VIN = 3.4V; other input at VCC or GND; IOUT=0 VCC = 5V, VIN = VCC or GND  DYNAMIC CHARACTERISTICS (tR, tF ≤ 3 ns;) MIN 2.0 4.4 3.94 TYP 4.5 4 MAX 0.8 0.1 0.36 ±0.1 2 UNIT V V V V μA μA 1.35 mA 10 pF PARAMETER Propagation delay from input (A and B) to output (Y) SYMBOL tPLH tPHL tPLH tPHL TEST CONDITIONS VCC =5±0.5 V, CL=15 pF VCC =5±0.5 V, CL=50 pF MIN TYP 5 5 5.5 5.5  OPERATING CHARACTERISTICS (VCC = 5V; TA=25°C, unless otherwise specified)) MAX 6.9 6.9 7.9 7.9 UNIT ns PARAMETER Power Dissipation Capacitance SYMBOL TEST CONDITIONS CPD No load, f=1MHz TYP UNIT 18 pF UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 3 of 4 QW-R502-415.C U74AHCT08  TEST CIRCUIT AND WAVEFORMS Note : CL includes probe and jig capacitance.
