They are specified in compliance with JEDEC standard no.
7A.
The 74HC/HCT20 provide the 4-input NAND function.
QUICK REFERENCE DATA GND = 0 V; Tamb = 25 °C; tr = tf = 6 ns TYPICAL SYMBOL tPHL/ tPLH CI CPD Notes 1.
CPD is used to determine the dynamic power dissipation (PD in µW): PD = CPD × VCC2 × fi + ∑ (CL × VCC2 × fo) where: fi fo = input frequency in MHz = output frequency in MHz PARAMETER propagation delay nA, nB, nC, nD to nY input capacitance power dissipation capacitance per package notes 1 and 2 CONDITIONS HC CL = 15 pF; VCC = 5 V 8 3.

5 17 ns pF pF UNIT CL = output load capacitance in pF VCC = supply voltage in V ∑ (CL × VCC2 × fo) = sum of outputs 2.
For HC the condition is VI = GND to VCC For HCT the condition is VI = GND to VCC − 1.
