tpd propagation nA to nY; see Fig. 4 [1] delay VCC = 4.5 V - 20 34 - 43 - 51 ns VCC = 5.0 V; CL = 15 pF - 17 - - - - - ns tt transition time VCC = 4.5 V; see Fig. 4 [2] - 7 15 - 19 - 22 ns CPD power per package; [3] - 8 - - - - - pF dissipation VI = GND to VCC - 1.5 V capacitance [1] tpd is the same as tPHL and tPLH. [2] tt is the same as tTHL and tTLH. [3] CPD is used to determine the dynamic power dissipation (PD in μW): PD = CPD × VCC 2 × fi × N + Σ (CL × VCC 2 × fo) where: fi = input frequency in MHz; fo = output frequency in MHz; CL = output load capacitance in pF; VCC = supply voltage in V; N = number of inputs switching; Σ (CL × VCC 2 × fo) = sum of outputs. 74HC_HCT14 All information provided in this document is subject to legal disclaimers. © Nexperia B.V. 2024.
