Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required package variant and temperature rating. Confirm that the 5.5 V tolerant inputs align with your system's signal levels to prevent damage. Ensure the 1.65 V to 3.6 V supply range is compatible with your power distribution network. Check for any recent product change notices regarding pinout or electrical specifications before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit width is necessary for data paths. The LVCH series is appropriate for designs requiring 3.3 V operation with 5 V tolerance. Consider the TVSOP package size if board real estate is limited compared to larger packages. Evaluate the 5.7 ns delay against your system clock requirements to ensure timing margins are sufficient for reliable operation.

Buffers, Drivers, Receivers, Transceivers Part Context
