Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DGVR' corresponds to the TVSOP-20 package and tape-and-reel quantity of 2000 units. Confirm RoHS compliance status and moisture sensitivity level (MSL) ratings prior to assembly planning. Ensure the selected variant matches the required operating temperature range of -40 °C to 85 °C for the target application environment.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring octal buffering within the 1.65 V to 3.6 V logic family. Consider the TVSOP-20 package constraints regarding thermal impedance and board space. Evaluate the need for separate output-enable controls for bus management versus simpler single-enable configurations found in other variants.

Buffers, Drivers, Receivers, Transceivers Part Context
