Procurement Notes

Verify the complete part number including the suffix J when ordering. Confirm that the required package variant matches the specific design constraints. Ensure the supplier provides valid traceability documentation. Check for RoHS compliance status as per current regulatory requirements. Validate the AEC-Q100 qualification certificate if automotive reliability is mandatory for the project.

Selection Notes

Select this component for designs requiring robust automotive-grade shift register functionality. Consider the 16-pin SO package dimensions for PCB layout compatibility. Evaluate the 3V to 15V supply voltage range against system power rails. Assess the 28MHz maximum frequency against signal timing requirements. Verify thermal performance capabilities within the specified -40°C to +125°C ambient range.
