Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DBR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 24-SSOP footprint matches the target PCB design constraints. Ensure the operating voltage requirements align with the system's 1.65V to 3.6V rail specifications before finalizing component selection.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require octal bus interfacing at sub-3.3V logic levels. The LVC series offers improved speed and lower power compared to older LV or LVT families. Consider the 24-SSOP package dimensions if space-constrained layouts are necessary. Verify that the input voltage thresholds remain compatible with the driving source logic levels within the specified supply range.
