Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle mixed voltage levels?

It supports 5V tolerant mixed-signal mode where inputs can be 3V or 5V, and outputs can be connected to either 3V or 5V buses.

What is the purpose of the balanced drive feature?

Balanced drives provide equal sink and source current capabilities to reduce ground bounce, match transmission lines, and lower EMI and RFI effects.
