Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the specific GR suffix corresponds to the TSSOP (DGG) package configuration required for your printed circuit board layout. Confirm the moisture sensitivity level and peak reflow temperature ratings align with your assembly process capabilities. Ensure all unused control inputs are properly terminated to VCC or GND during operation to guarantee correct device functionality.

Buffers, Drivers, Receivers, Transceivers Selection Notes
