Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature range. Confirm that the component status aligns with current production requirements. Check for any recent revision history updates that may affect specifications. Ensure compliance with RoHS directives if applicable to the target market.

Selection Notes

Select this component when TTL-level inputs must interface with CMOS outputs. The HCT series ensures compatibility with standard TTL logic families. Consider the wide operating temperature range for harsh environments. Verify that the dual gate configuration meets the circuit design requirements efficiently.

Part Context

This part belongs to the Nexperia 74HC/HCT2Gxx series of dual logic gates. It shares functional similarities with other NOR gates in the family but is distinguished by its HCT technology. The GD suffix indicates a specific surface-mount package variant within the broader product line.

Replacement Considerations

Compatible substitutes include the 74HC2G02GD for CMOS-level inputs and other dual NOR gates from the same manufacturer's portfolio. Verify pinout compatibility and electrical characteristics before substitution.
