By using LTC4314 I2C Multiplexer, I aim to transfer data I send i2c to 4 channels with selectable pins. When I examined the document, a few pins came to my mind.
What exactly do the ACC, DISCEN and FAULT pins do? I understand from the document that it is related to the output rise time of the ACC pin, which I fully understand. The FAULT pin can be observed when an error is detected, but what does the DISCEN pin do? I left the FAULT pin in the HIGH state, the ACC pin in the low state, but I did not fully understand what would change if I set the DISCEN pin HIGH and LOW. It is usually left in the HIGH state in the document, but there is no complete information about why it was left.
In addition, there is no information about whether the ENABLE pins will be in HIGH state during data transfer and then go back to LOW state or whether it should be HIGH-LOW before starting data transfer, even there is no data transmission image. How will the data coming from the input side be transferred to the output side using ENABLE pins?
