74AHCT02D,118

Overview

The Nexperia 74AHCT02D,118 is a high-speed Si-gate CMOS quad 2-input NOR gate compliant with JEDEC standard No. 7-A and pin-compatible with LSTTL. It operates within a supply voltage range of 4.5 V to 5.5 V. The device features balanced propagation delays ranging from 5.1 ns to 9.5 ns depending on load capacitance. It includes Schmitt-trigger inputs, ESD protection exceeding 2000 V (HBM) and 1000 V (CDM), and functions across an ambient temperature range of -40 °C to +125 °C in a 14-lead SOIC package.

Feature Summary

• Provides a quad 2-input NOR logic function
• All inputs feature Schmitt-trigger action for noise immunity
• Inputs accept voltages higher than the supply voltage (VCC)
• ESD protection exceeds 2000 V via Human Body Model and 1000 V via Charged Device Model

Applications

• General-purpose digital logic circuits requiring NOR functionality
• Systems interfacing TTL-level signals with CMOS logic families
• High-speed data processing applications utilizing balanced propagation delays

Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature range. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design parameters align with the absolute maximum ratings defined in the product data sheet to prevent device stress or permanent damage during operation.

Selection Notes

Select this component when a quad 2-input NOR gate is required with TTL-compatible input levels. The AHCT series ensures compatibility with Low-power Schottky TTL (LSTTL) systems while offering CMOS performance characteristics. Consider the 14-SOIC package dimensions and thermal dissipation requirements relative to the application environment.

Part Context

This part belongs to the 74AHC/AHCT logic family, designed for high-speed CMOS applications. The 'D' suffix indicates the SO14 plastic small outline package variant. The '118' suffix denotes the specific tape and reel packaging configuration used for automated surface-mount assembly processes.

Replacement Considerations

The 74AHC02D,118 serves as the CMOS-level equivalent within the same package. Cross-vendor equivalents such as the SN74AHCT02N are available but require verification of pinout and electrical specifications against the original datasheet.
