Note 1:
The pin’s “smart” pull-up shuts off while the pin is forced low. This is done to reduce the standby and shut-
down current.
2:
The DFN and QFN packages have 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 VSS pin.
