Quad 2-input NOR gate
Product specification
74AHC02; 74AHCT02
FEATURES
ESD protection:
HBM EIA/JESD22-A114-A
exceeds 2000 V
MM EIA/JESD22-A115-A
exceeds 200 V
CDM EIA/JESD22-C101
exceeds 1000 V
Balanced propagation delays
All inputs have Schmitt-trigger
actions
Inputs accepts voltages higher than
VCC
For AHC only:
operates with CMOS input levels
For AHCT only:
operates with TTL input levels
Specified from
40 to +85 and +125 °C.
DESCRIPTION
The 74AHC/AHCT02 are high-speed
Si-gate CMOS devices and are pin
compatible with low power Schottky
TTL (LSTTL). They are specified in
compliance with JEDEC standard
No. 7A.
The 74AHC/AHCT02 provides the
Quad 2-input OR function.

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 × VCC2 × fo) = sum of outputs;
CL = output load capacitance in pF;
VCC = supply voltage in Volts.
2. The condition is VI = GND to VCC.
