PIN TYPES
Pin Type
Description
Power
This pin is used to supply power or ground to the device.
DI
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.
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.
