Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix DGGR confirms the TSSOP-56 package and reel packaging configuration. Ensure compatibility with the target PCB footprint and thermal requirements. Confirm that the 1.65 V to 3.6 V operating range aligns with the system power rails. Check for any specific RoHS compliance documentation if required by regional regulations.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a combined transceiver and register solution is needed for 16-bit wide buses. It is suitable for applications requiring low voltage operation down to 1.65 V. Consider the 7.9 ns propagation delay for timing constraints. The TSSOP-56 package offers a compact form factor for space-constrained designs compared to larger packages.
