Hi Bhavish,

What is VCCA and VCCB connected to? Is it possible to swap the power supplies so that it follows standard device operation?

Hello Jack,

Thank you for replying

In my design we have connected VCCA to 3V3 and VCCB to 1V8, as per the condition VCCA must not exceed VCCB,
we cannot do any work around as signals will get swapped, we cannot go for layout change immediately
can you suggest any alternate part or any other solution for this issue

Bhavish

Hi Bhavish,

If your signals are utilizing push-pull driver architectures, the TXU0x02 can be used here as drop in replacement/ alternative part supporting VCCA> VCCB.
