Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the component meets the intended automotive grade requirements. Ensure compatibility with existing design specifications regarding voltage levels and thermal management constraints before finalizing procurement decisions.

Selection Notes

Select this component when TTL logic levels are required for NOR gate functionality. Consider the SO-14 package dimensions for PCB layout. Evaluate the power dissipation capabilities against the expected switching frequency and load conditions to ensure operation remains within specified limits.

Part Context

This part belongs to the Nexperia 74HCT02-Q100 family of quad 2-input NOR gates. It shares functional characteristics with other variants in the series but differs in packaging options such as TSSOP or DHVQFN. The D suffix specifically denotes the SO-14 plastic small outline package configuration.

Replacement Considerations

Direct substitutes include other 74HCT02-Q100 variants with different packages, such as 74HCT02PW-Q100 (TSSOP14) or 74HCT02BQ-Q100 (DHVQFN14). Verify pinout compatibility and physical footprint differences when considering alternative package types.
