SN74HC02AN

Overview

The SN74HC02AN is a quadruple 2-input positive-NOR gate manufactured by Texas Instruments. It belongs to the HC logic series and utilizes CMOS technology. The device operates within a supply voltage range of 2 V to 6 V. It features four independent NOR gates, each with two inputs. The package type is SOIC-14 (Small Outline Integrated Circuit). The low-level output current is specified at 5.2 mA, while the high-level output current is -5.2 mA. The propagation delay is typically 8 ns. The operating temperature range extends from -40 °C to +85 °C.

Feature Summary

• Provides four independent 2-input NOR logic functions in a single integrated circuit
• Operates across a wide supply voltage range suitable for various digital systems
• Features standard push-pull outputs for driving loads

Applications

• Digital logic circuits requiring NOR functionality
• Signal processing applications involving boolean logic operations
• General-purpose electronic designs utilizing HC series logic

Procurement Notes

Verify the specific suffix 'AN' against the manufacturer's official datasheet to confirm the package style and tape/reel specifications. Ensure the component meets RoHS compliance requirements if mandated by the design. Cross-reference the ordering information with the latest Texas Instruments documentation to avoid discrepancies in packaging or lead times.

Selection Notes

Select this component when a quadruple 2-input NOR gate is required within the HC logic family. Consider the SOIC-14 package dimensions for PCB layout constraints. Verify that the 2 V to 6 V supply voltage range aligns with the system power rails. Check the propagation delay specifications against the timing requirements of the application.

Part Context

This part is part of the SNx4HC02 family of quadruple 2-input positive-NOR gates. It shares functional characteristics with other HC series devices but is distinct in its specific logic function. The 'A' suffix typically denotes an improved version or specific manufacturing revision compared to earlier iterations.

Replacement Considerations

Compatible substitutes include SN74HC02DR and SN74HC02N. Verify pin compatibility and electrical parameters before substitution.
