Note 1: Data in “Typical” column is at 3.3V, 25°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 “Pin List” section for the 5V-tolerant pins.
6: The V
IH specifications are only in relation to externally applied inputs, and not with respect to the user-
selectable internal pull-ups. External open drain input signals utilizing the internal pull-ups of the device are
provided to be recognized only as a logic “high” internally to the device. For External “input” logic inputs
that require a pull-up source, to ensure the minimum V
IH of those components, it is recommended to use
an external pull-up resistor rather than the internal pull-ups of the device.
