Selection Notes

Select this component when a dual 4-input NOR function is required with TTL-compatible inputs. Ensure the design accommodates the 4.5 V to 5.5 V supply voltage range. Verify that the SSOP-14 package dimensions fit the PCB layout constraints. Confirm thermal management requirements for operation up to +125 °C ambient temperature.

Part Context

This part belongs to the Nexperia 74HCT4002 product line, which includes variants in SO14 and TSSOP14 packages. The HCT series is designed for compatibility with standard TTL logic families while utilizing CMOS technology for lower power dissipation. The DB suffix specifically denotes the SSOP14 plastic shrink small outline package variant.

Replacement Considerations

Cross-reference with other manufacturers' 74HCT4002 equivalents ensuring pinout compatibility with SOT337-1. Verify electrical parameters match the required supply voltage and speed specifications.
