Shift Registers Procurement Notes

Verify the specific suffix Q1 indicates automotive grade compliance when sourcing. Confirm the WQFN-16 package dimensions match your PCB footprint requirements. Ensure the operating voltage aligns with your system's 2 V to 5.5 V specification. Check for RoHS compliance status if required by your manufacturing standards. Validate the lead time against production schedules as automotive parts may have longer availability windows.

Shift Registers Selection Notes

Select this component when designing automotive logic circuits requiring robust shift register functionality. It is appropriate for applications needing serial data input converted to parallel outputs with high noise immunity. Consider the HCT logic family compatibility if interfacing with 5 V TTL devices. Evaluate the thermal performance within the specified -40°C to +125°C range for your enclosure design.

Shift Registers Part Context
