PIN TYPE DESCRIPTION
Power This pin is used to supply power or ground to the device.
AIO Analog Input / Output -This pin is used as an I/O for analog signals.
DI Digital Input - This pin is used as a digital input. This pin is 5V tolerant.
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.
OD 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.
