74HC/HCT4002
The 74HC/HCT4002 are high-speed Si-gate CMOS devices and are pin compatible with “4002” of the “4000B” series. They are specified in compliance with JEDEC standard no. 7A. The 74HC/HCT4002 provide the 4-input NOR 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 W): PD = CPD × VCC2 × fi + ∑ (CL × VCC2 × fo) where: fi = input frequency in MHz fo = output frequency in MHz ∑ (CL × VCC2 × fo) = sum of outputs CL = output load capacitance in pF VCC = supply voltage in V 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”.
