Part Number: TCA9509

Hello E2E,

I am curious, can you swap SDAA and SCLA?  Or SDAB with SCLB?  It seems like all of their specs are the same in the electrical char. section of the datasheet.  What would happen if you applied a data signal on the designated clocking pin and vice/versa?

  • Hey Russell,

    That's fine. The SDA and SCL channels are designed identically. If swapping them makes the PCB layout easier, then you can swap them.
