Procurement Notes

Verify the exact suffix against the manufacturer's official datasheet to confirm pinout compatibility and electrical specifications. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check for obsolescence notices or end-of-life notifications from onsemi before finalizing procurement plans.

Selection Notes

Select this component for designs requiring dual 8-bit storage with tri-state control in low-voltage environments. Ensure the 1.65V to 3.6V supply range aligns with system power rails. Consider the 48-TSSOP package constraints for PCB layout and thermal management during high-frequency operation.
