SN74HC02DRE4

Overview

The SN74HC02DRE4 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. Key electrical parameters include a low-level output current of 5.2 mA, a high-level output current of -5.2 mA, and a propagation delay of 18 ns. It supports an operating temperature range from -40°C to +125°C and is housed in a 14-SOIC package.

Feature Summary

• Contains four independent 2-input NOR gates for complex logic implementation
• CMOS construction ensures low power consumption and high noise immunity
• Wide operating voltage range supports diverse system power requirements
• Extended temperature rating enables reliable operation in harsh environments

Applications

• Automotive electronic control units requiring AEC-Q100 qualified components
• Industrial automation systems with wide temperature demands
• Consumer electronics utilizing standard logic interfaces
• Telecommunications equipment requiring robust signal processing

Procurement Notes

Verify the specific ordering suffix to confirm the exact package type and tape-and-reel specifications. Ensure the component meets the required automotive qualification standards if used in safety-critical applications. Cross-reference the datasheet revision date to confirm compatibility with current design constraints. Confirm RoHS compliance status matches project environmental regulations before finalizing procurement orders.

Selection Notes

Select this component when a quadruple NOR gate configuration is required within the HC logic family. Consider the 14-SOIC package for surface-mount assembly needs. Evaluate the 2 V to 6 V supply range against system power availability. Compare propagation delay characteristics against timing requirements of the target application circuit.

Part Context

This part is part of the SNx4HC02 family of quadruple 2-input positive-NOR gates. It shares functional similarities with other HC series logic devices but offers specific automotive qualification through the Q1 suffix variant. The DRE4 designation indicates a specific tape-and-reel packaging format suitable for automated surface-mount production lines.

Replacement Considerations

SN74HC02DR serves as a direct pin-compatible alternative within the same manufacturer's portfolio. Other HC-series NOR gates may require logic inversion adjustments. Verify package dimensions and electrical characteristics before substituting with non-TI manufacturers.
