Thanks for the quick reply Jonathan.
One additional question. When changing the state of a pin from input to output, does the PCA9534A put the pin in “high” output state by default, before we change it to “low”?

Hi Nihar,
What voltages you are using for SDA/SCL, VCC and SD0/SC0 and what pull-ups are you using for the I2C buses?
Also, can you attempt to read back from the PCA9534A and let me know what the response is?

I have now had the time to verify that the TCA6408A does indeed solve the above mentioned issue :-) I have not tested it extensively yet, but everything seems to work as intended. I will let you know in case I find…
Other Parts Discussed in Thread: PCA9534A While evaluating the PCA9534A, I am able to configure its pins as outputs and output the desired logic level, but when configuring as ports as inputs, I always read 0 logic level from the inputs.
