Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant (TVSOP-20) and suffix (DGVR) against the official datasheet to ensure compatibility with PCB footprint requirements. Confirm that the operating voltage range of 2.7 V to 3.6 V aligns with the target system power rails. Check for RoHS compliance status as indicated in the manufacturer's documentation before finalizing procurement specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring octal bidirectional data transfer with LVTTL compatibility. Ensure the design accommodates the specified 64 mA low-level sink current capability. Verify that the 5.1 ns propagation delay meets the timing constraints of the application. Consider the TVSOP-20 package dimensions for thermal management and board space allocation during the layout phase.
