INTEGRATED CIRCUITS DATA SHEET 74AHC02; 74AHCT02 Quad 2-input NOR gate Product specification Supersedes data of 1998 Dec 18 File under Integrated Circuits, IC06 1999 Sep 23 Philips Semiconductors Product specification Quad 2-input NOR gate 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.

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.
