Note 1: Data in âTypicalâ column is at 3.3V, 25Â°C unless otherwise stated. Parameters are for design guidance only

and are not tested.

2: The leakage current on the MCLR pin is strongly dependent on the applied voltage level. The specified

levels represent normal operating conditions. Higher leakage current may be measured at different input

voltages.

3: Negative current is defined as current sourced by the pin.

4: This parameter is characterized, but not tested in manufacturing.

5: See the âPin Diagramsâ section for the 5V-tolerant pins.
