tTLH, tTHL Transition times CL = 50pF 4.5 15 19 22 ns
CIN Input capacitance 10 10 10 pF
CPD Power dissipation capacitance(1)(2) 5 42 pF
CPD is used to determine the dynamic power consumption, per gate.
PD = VCC2 fi (CPD + CL) where fi = Input Frequency, CL = Output Load Capacitance, VCC = Supply Voltage.
