Other Parts Discussed in Thread: PCA9517
PCA9517: I2C Level-translating Bus Repeater. We are using it for SMBus.
The component on the A side of the chip had a mistake in the SMBus pinout, so on my board SCL is wired to pin 3 (SDAA) and SDA is wired to pin 2 (SCLA).
The B side is wired correctly.
It is much easier and more reliable to swap the lines on the B side of the chip. This means that SCL would be traveling through the buffers meant for SDA, and SDA through the SCL buffers.
The chip datasheet shows two bidirectional buffers with no control logic. But we are worried that the chip is not as simple as that, and that there is logic that will cause errors when we use it backwards.
What do the experts think?
