Legend:
HV w/ST = High Voltage tolerant input (with Schmitt trigger input)
A = Analog pins (Potentiometer terminals)
O = digital output
P = Power
Note 1:
The pin’s “smart” pull-up shuts off while the pin is forced low. This is done to reduce the standby and
shutdown current.
2:
The QFN package has a contact on the bottom of the package. This contact is conductively connected to
the die substrate, and therefore should be unconnected or connected to the same ground as the device’s
V
pin.
