OD
Open-drain output. An external pull-up resistor is required if this pin is used as an output.
NPU
N-channel pull-up. This pin will pull-up to approximately VDD - 1.0V when outputting a logical ‘1’.
PU
Weak internal pull-up (10K-50K ohms)
No-P diode
No P-diode to VDD. This pin may be pulled above the supply rail (to 6.0V maximum).
AN
