Hi all,

I would like to ask a question of configuration.

Is it possible the connection configuration as shown below?

Can I connect TCA9803 from BUS B in parallel?

Best Regards,

This is allowed as long as no two B sides are connected together. So in this case, all four TCA980x devices must have the A side on the left.

Hi Ryusuke,

As Clemens mentioned, this type of connection is fine as long as no two B-sides are connected together.

The TCA980x devices that branch off from figure 34 should have their A-sides connect to that part of the bus.

Regards,

Tyler
