They are specified in compliance with JEDEC standard no. 7A. The 74HC/HCT02 provide the 2-input NOR function. QUICK REFERENCE DATA GND = 0 V; Tamb = 25 °C; tr = tf = 6 ns TYPICAL SYMBOL PARAMETER CONDITIONS UNIT HC CL = 15 pF; VCC = 5 V HCT tPHL/ tPLH propagation delay nA, nB to nY 7 9 ns CI input capacitance 3.5 3.5 pF CPD power dissipation capacitance per gate notes 1 and 2 22 24 pF Notes 1. CPD is used to determine the dynamic power dissipation (PD in µW): PD = CPD × VCC2 × fi + ∑ (CL × VCC2 × fO) where: fi = input frequency in MHz fo = output frequency in MHz 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 − 1.5 V ORDERING INFORMATION See “74HC/HCT/HCU/HCMOS Logic Package Information”.

Output capability: standard ICC category: SSI Notes to HCT types The value of additional quiescent supply current (∆ICC) for a unit load of 1 is given in the family specifications. To determine ∆ICC per input, multiply this value by the unit load coefficient shown in the table below.
