SN74HC02DRG4

Overview

The SN74HC02DRG4 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, housed in a 14-pin SOIC package. Key electrical characteristics include a propagation delay of 8 ns, a low-level output current of 5.2 mA, and a high-level output current of -5.2 mA. The component supports surface-mount installation and functions reliably across an operating temperature range from -40 °C to +85 °C.

Feature Summary

• Contains four independent 2-input positive-NOR logic gates
• Operates on standard CMOS technology for low power consumption
• Supports wide supply voltage operation from 2 V to 6 V

Applications

• Digital signal processing circuits requiring logical NOR operations
• General-purpose logic control systems
• Embedded system interface design

Procurement Notes

Verify the specific ordering suffix 'G4' against the manufacturer's official documentation to confirm compliance with RoHS directives and lead-free manufacturing standards. Ensure the package type matches the required PCB footprint. Confirm that the active status aligns with long-term availability requirements for the intended production cycle.

Selection Notes

Select this component when a quadruple 2-input NOR function is required within the HC logic family specifications. Consider the 14-pin SOIC package constraints and the 2 V to 6 V operating voltage range. Evaluate the 8 ns propagation delay against the target circuit speed requirements. Verify thermal performance within the specified -40 °C to +85 °C industrial temperature range.

Part Context

This part is a variant of the SN74HC02 series, distinguished by the 'D' indicating the SOIC-14 package and 'RG4' denoting tape-and-reel packaging with green/RoHS-compliant materials. It serves as a standard discrete logic solution for implementing complex Boolean functions in digital electronics. The HC series provides compatibility with previous TTL logic levels while offering improved noise immunity and lower power dissipation compared to older technologies.

Replacement Considerations

Direct pin-compatible substitutes include SN74HC02DR and SN74HC02N. Cross-vendor equivalents such as MC74HC02ADR or CD74HC02M may be considered if electrical parameters match exactly.
