74AHC1G02W5-7

Overview

The 74AHC1G02W5-7 is a single 2-input positive NOR gate from the AHC logic series, manufactured by Diodes Incorporated. It operates within a supply voltage range of 2.0V to 5.5V and features standard push-pull outputs capable of ±8 mA drive current at 5.0V. The device utilizes Schmitt trigger inputs for noise tolerance and provides ESD protection exceeding 2000V (HBM) and 200V (MM). Propagation delay ranges from 4.6 ns to 9.5 ns depending on load capacitance and temperature. It is housed in an SOT-25 package.

Feature Summary

• Single 2-input positive NOR gate with standard push-pull output configuration
• Schmitt trigger action at all inputs for improved noise immunity
• High ESD protection ratings across multiple testing standards
• CMOS technology ensuring low power consumption

Applications

• General purpose logic circuits
• PCs, networking equipment, notebooks, and netbooks
• Computer peripherals including hard drives and CD/DVD ROMs
• TV, DVD, DVR, and set-top boxes
• Personal navigation/GPS devices and MP3 players

Procurement Notes

Verify the specific package suffix matches the required footprint; W5 indicates SOT-25 while SE indicates SOT-353. Confirm RoHS compliance status as per the manufacturer's latest documentation. Ensure ordering quantities align with the standard 3000-unit tape and reel packaging format provided by Diodes Incorporated.

Selection Notes

Select this component when a compact single-gate NOR solution is required for portable or high-density designs. The wide operating voltage range supports various digital logic families. Verify that input transition rates remain within specified limits to maintain signal integrity without external buffering.

Part Context

This part belongs to the 74AHC1G series of single-function gates designed for space-constrained applications. It offers performance comparable to older logic families while consuming significantly less power. The series includes inverters, buffers, and various logic functions in ultra-small packages.

Replacement Considerations

The 74AHC1G02SE-7 serves as a direct functional substitute utilizing the SOT-353 package instead of SOT-25. Cross-reference pinouts carefully as physical dimensions differ between package types despite identical electrical characteristics.

FAQ
