Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix DCKR to confirm the SC-70-5 package type and tape-and-reel quantity. Ensure compatibility with the target voltage domain, as the AUP series supports a wide range down to 0.8 V. Confirm RoHS compliance status through official manufacturer documentation prior to integration into regulated assemblies.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when design constraints require ultra-low power dissipation combined with small form factor packaging. The AUP series offers superior speed-per-watt performance compared to older LVC or LV technologies. Consider the 0.8 V minimum supply requirement to ensure proper functionality in low-voltage environments where standard 1.8 V parts may not operate correctly.
