DESCRIPTION

Power

This pin is used to supply power or ground to the device.

Digital Input - This pin is used as a digital input. This pin is 5V tolerant.

AIO

Analog Input / Output - This pin is used as an I/O for analog signals.

DIOD

Digital Input / Open Drain Output - This pin is used as a digital I/O. When it is used as an

output, it is open drain and requires a pull-up resistor. This pin is 5V tolerant.

Open Drain Digital Output - This pin is used as a digital output. It is open drain and requires

a pull-up resistor. This pin is 5V tolerant.
