Procurement Notes
Verify the specific suffix 'D' corresponds to the SOIC-14 package variant during procurement. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the ordering part number matches the exact SN74HC02D designation to avoid pinout or electrical specification mismatches. Cross-reference datasheet revisions for any updates on recommended operating conditions.
Selection Notes
Select this component when a quadruple 2-input NOR configuration is required in a surface-mount format. The HC series offers compatibility with standard CMOS logic levels while maintaining low power dissipation. Consider the 14-SOIC package dimensions for PCB layout constraints. Verify that the 60 MHz speed rating meets the system timing requirements for the intended application.
Part Context
This device belongs to the SNx4HC02 family of quadruple 2-input positive-NOR gates produced by Texas Instruments. The HC series represents high-speed CMOS technology designed for general-purpose digital applications. The 'D' suffix specifically denotes the plastic small-outline package type. This family is widely used in computing and industrial automation for reliable logic processing.
Replacement Considerations
Compatible substitutes include CD74HC02M96 and SN74HC02DR. Verify pin compatibility and electrical specifications before substitution. Ensure the alternative part maintains the same logic function and package footprint.
