SN74F02NG4

Overview

The SN74F02NG4 is a quadruple 2-input positive-NOR gate from the Texas Instruments F logic family. It operates within a supply voltage range of 4.5 V to 5.5 V, with high-level input voltage at 2 V and low-level input voltage at 0.8 V. Output drive capabilities include -1 mA for high state and 20 mA for low state. Propagation delay ranges from 1 ns to 6.5 ns under standard load conditions. The device functions across an operating temperature range of 0°C to 70°C.

Feature Summary

• Contains four independent 2-input NOR gates performing Boolean OR functions in positive logic
• Features robust output drive capability suitable for direct interfacing with TTL loads
• Provides fast switching speeds characteristic of the F logic series

Applications

• General-purpose digital logic circuits requiring NOR functionality
• Signal processing systems utilizing positive logic configurations
• Industrial control applications compatible with standard 5V logic levels

Procurement Notes

Verify that the ordering suffix 'G4' corresponds to lead-free packaging and RoHS compliance as defined by Texas Instruments standards. Confirm the package type matches the required PCB footprint. Ensure the component status aligns with current production availability before finalizing procurement plans.

Selection Notes

Select this component when specific NOR gate functionality is required within the F logic speed class. Consider the 14-pin PDIP package for through-hole mounting requirements. Evaluate power consumption and propagation delay specifications against system timing constraints to ensure compatibility with existing circuit designs.

Part Context

This part belongs to the SN74F02 family of quadruple 2-input NOR gates manufactured by Texas Instruments. The F logic series is designed for high-speed applications compared to standard 74 series devices. The 'N' suffix indicates a plastic dual-in-line package, while 'G4' denotes environmental compliance features.

Replacement Considerations

SN74F02N serves as a direct functional equivalent without the G4 suffix. Other variants such as SN74F02DR or SN74F02NSR offer identical logic functions but utilize surface-mount packages instead of through-hole DIP.
