Note 7.5 This specification applies to all inputs and tri-stated bi-directional pins. Internal pull-down
and pull-up resistors add +/- 50uA per-pin (typical).
Note 7.6
This is the total V_IN input leakage for the entire device. This value should be divided by
the number of pins driven to V_IN MAX to calculate per-pin leakage. For example, if 10 pins
are driven to the maximum operational limit for V_IN, the per-pin input leakage is the
maximum input leakage current divided by 10.
