TCA9545A: I2C pullup resistors on output channels

Part Number: TCA9545A

Hi,

We are using a TCA9545A as an I2C switch. We are not using the voltage translation feature, all I2C channels use the same 3.3V supply. From the data sheet it looks like additional pullup resistors are still needed on all the four output channels. But I am not sure, can you verify?

Thanks,

Joe
