3 / 8 page TC74ACT14P/F/FN/FT 2007-10-01 3 Operating Ranges (Note) Characteristics Symbol Rating Unit Supply voltage VCC 4.5 to 5.5 V Input voltage VIN 0 to VCC V Output voltage VOUT 0 to VCC V Operating temperature Topr −40 to 85 °C Note: The operating ranges must be maintained to ensure the normal operation of the device. Unused inputs must be tied to either VCC or GND. Electrical Characteristics DC Characteristics Test Condition Ta = 25°C Ta = −40 to 85°C Characteristics Symbol VCC (V) Min Typ. Max Min Max Unit Positive threshold voltage VP ― 4.5 ― ― 2.0 ― 2.0 V Negative threshold voltage VN ― 4.5 0.8 ― ― 0.8 ― V Hysteresis voltage VH ― 4.5 0.4 ― 1.2 0.4 1.2 V High-level output voltage VOH VIN = VIL IOH = −50 μA IOH = −24 mA IOH = −75 mA (Note) 4.5 4.5 5.5 4.4 3.94 ― 4.5 ― ― ― ― ― 4.4 3.80 3.85 ― ― ― V Low-level output voltage VOL VIN = VIH IOL = 50 μA IOL = 24 mA IOL = 75 mA (Note) 4.5 4.5 5.5 ― ― ― 0.0 ― ― 0.1 0.36 ― ― ― ― 0.1 0.44 1.65 V Input leakage current IIN VIN = VCC or GND 5.5 ― ― ±0.1 ― ±1.0 μA ICC VIN = VCC or GND 5.5 ― ― 4.0 ― 40.0 μA Quiescent supply current IC Per input: VIN = 3.4 V Other input: VCC or GND 5.5 ― ― 1.35 ― 1.5 mA Note: This spec indicates the capability of driving 50 Ω transmission lines. One output should be tested at a time for a 10 ms maximum duration. AC Characteristics (CL = 50 pF, RL = 500 Ω, input: tr = tf = 3 ns) Test Condition Ta = 25°C Ta = −40 to 85°C Characteristics Symbol VCC (V) Min Typ. Max Min Max Unit Propagation delay time tpLH tpHL ― 5.0 ± 0.5 ― 7.2 11.4 1.0 13.0 ns Input capacitance CIN ― ― 5 10 ― 10 pF Power dissipation capacitance CPD (Note) ― 30 ― ― ― pF Note: CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating current consumption without load. Average operating current can be obtained by the equation: ICC (opr) = CPD·VCC·fIN + ICC/6 (per gate) |
