74HC/HCT4002; Dual 4-input NOR gate
Philips Semiconductors Product specification
Dual 4-input NOR gate 74HC/HCT4002
FEATURES Output capability: standard ICC category: SSI
GENERAL DESCRIPTIONThe 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 DATAGND= 0 V; Tamb =25 °C; tr =tf= 6 ns
Notes CPD is used to determine the dynamic power dissipation (PD in μW): =CPD× VCC2×fi +∑ (CL× VCC2× fo) where:= input frequency in MHz= output frequency in MHz (CL× VCC2×fo)= sum of outputs= output load capacitance in pF
VCC= supply voltage in V For HC the condition is VI= GND to VCC
For HCT the condition is VI= GND to VCC− 1.5 V
