Procurement Notes

Verify the specific suffix against official Nexperia documentation to confirm package type and tape-and-reel specifications. Ensure the procurement channel sources components directly from authorized distributors to guarantee authenticity. Confirm that the delivered parts match the AEC-Q100 grade requirements for your target application. Check for any recent product change notices regarding marking or assembly updates.

Selection Notes

Select this component when TTL-level inputs are required alongside CMOS outputs in automotive contexts. The HCT series ensures compatibility with standard logic families while maintaining low power consumption. Verify that the SO14 package dimensions fit the available PCB real estate. Consider the thermal performance at maximum ambient temperatures within the specified range.

Part Context

This part belongs to the 74HCT family of high-speed CMOS logic devices manufactured by Nexperia. The 74HCT series bridges the gap between older TTL logic and modern CMOS technology. It offers improved noise immunity and lower power dissipation compared to legacy counterparts. The automotive variant ensures reliability in vehicle electronics.

Replacement Considerations

Check for equivalent parts such as the 74HC32D if TTL input compatibility is not strictly required. Verify pinout compatibility before substituting with other manufacturers' OR gates. Ensure the replacement meets the same AEC-Q100 qualification level.
