Procurement Notes

Verify that the ordering suffix matches the required packaging configuration, as variations exist between cut tape, reel, and specific distributor formats. Confirm AEC-Q100 qualification requirements if automotive compliance is necessary, noting that specific suffixes may denote different reliability grades. Ensure the procurement source provides official datasheets to validate pinout compatibility and electrical characteristics against the target design specifications.

Selection Notes

Select this component when designing circuits requiring 16-bit parallel data latching at low voltages. It is suitable for applications needing direct interface with 5 V devices despite lower operating voltages. Consider the TSSOP-48 package constraints regarding thermal dissipation and PCB space. Evaluate the bus-hold feature benefits against designs that already utilize external pull-up resistors to optimize bill of materials.

Part Context

This part belongs to the Nexperia 74LVCH series, which focuses on low-voltage, high-speed CMOS logic solutions. The LVCH family is engineered for applications demanding reduced power consumption while maintaining performance comparable to higher voltage counterparts. It complements other 16-bit logic families by offering specific interface capabilities tailored for modern portable and battery-operated electronic devices.

Replacement Considerations

Cross-reference with the 74LVC16374ADGG variant for standard LVC performance or the 74LVTH16374ADGG for enhanced drive strength. Verify package dimensions and pin assignments to ensure mechanical compatibility during substitution. Check manufacturer documentation for any updates regarding lead-free status or environmental compliance changes.
