Translators, Level Shifters FAQ

What is the function of the separate A and B ports?

The A and B ports connect to independent power supplies (VCCA and VCCB), allowing the device to translate signals between two different voltage domains simultaneously.

How does the direction control pin operate?

The direction control pin determines the data flow direction between port A and port B, enabling bidirectional communication on the bus.
