Capacitive Loading Specifications on Output Pins
D101A* CIO All I/O Pins — — 50 pF
* These parameters are characterized but not tested.
† Data in “Typ” column is at 3.0V, +25°C unless otherwise stated. These parameters are for design guidance only and are
not tested.
Note 1: Negative current is defined as current sourced by the pin.
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.
