SN74HC02NG4

Overview

The SN74HC02NG4 is a quadruple 2-input positive-NOR gate manufactured by Texas Instruments. It belongs to the HC logic family and utilizes CMOS process technology. The device operates within a supply voltage range of 2 V to 6 V. Key electrical parameters include a maximum low-level output current of 5.2 mA and a maximum high-level output current of -5.2 mA. Propagation delay is specified at 18 ns under typical conditions. The component supports an operating temperature range from -40°C to +85°C and is housed in a 14-pin PDIP package.

Feature Summary

• Contains four independent 2-input NOR logic gates within a single integrated circuit.
• Utilizes advanced CMOS technology for compatibility with standard TTL levels while maintaining low power consumption.
• Features push-pull outputs capable of driving moderate loads across a wide supply voltage range.

Applications

• Digital logic circuits requiring NOR functionality
• Signal processing in automotive electronic systems
• General-purpose computing and control logic

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free composition and RoHS compliance as per manufacturer standards. Confirm the 'N' designation corresponds to the PDIP-14 through-hole package variant. Ensure the order quantity matches the tube packaging format typically associated with this part number. Cross-reference the date code and manufacturing origin if long-term availability is required for production runs.

Selection Notes

Select this component when a quadruple 2-input NOR configuration is required in a through-hole format. The HC series offers speed and power characteristics suitable for general digital applications. Consider the 2 V to 6 V operating range for flexibility in system design. Verify that the 14-pin DIP footprint aligns with the target PCB layout constraints.

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 is distinct in its NOR logic function. The 'G4' suffix typically denotes environmental compliance, while 'N' specifies the package type. It serves as a fundamental building block for complex digital logic designs.

Replacement Considerations
