Hi TI teams,

Refer the datasheet: B-side ports must not be connected together.

We have concern if we A-side is cascaded A side. Is it fine for design?

Please refer our design diagram as below. Thanks.

Hi Helen,

As Clemen's pointed out, this configuration/set up is allowed. With static voltage offset buffers, static voltage offset sides (B side of TCA9517) cannot connect to other static voltage offsets on the offset side. A side of TCA9517 does not have an offset, only B side does.
