Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix RGYR corresponds to the VQFN-20 package and reel packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the operating voltage range aligns with your system's power rails. Check for any lead-free or environmental certifications required by your procurement standards before finalizing orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require ultra-low voltage operation below 1.8 V while maintaining high-speed performance. The AUC series offers lower power consumption compared to standard AHC or LVC families. Consider the VQFN-20 package for space-constrained PCB layouts. Ensure the 9 mA drive capability meets the load requirements of your connected components without exceeding thermal limits.
