What voltage ranges does it support?

Both VCCA and VCCB ports support any supply voltage from 1.65 V to 5.5 V.

How is the direction of data flow controlled?

The direction is controlled by the DIR input pin: a logic HIGH allows data transmission from A to B, and a logic LOW allows transmission from B to A.

What should engineers review before using this device?

Engineers should ensure that the DIR pin is properly driven to avoid bus contention and that bypass capacitors are used on both power supply rails.
