Data in “Typ” column is at 5V, 25C unless otherwise stated. These parameters are for design guidance only and are not tested.
In EXTRC oscillator configuration, the OSC1/CLKIN pin is a Schmitt Trigger input. It is not recommended that the
PIC16F526 be driven with external clock in RC mode.
Negative current is defined as coming out of the pin.
This spec. applies to RB3/MCLR configured as RB3 with pull-up disabled.
This spec. applies to all weak pull-up devices, including the weak pull-up found on RB3/MCLR. The current value listed
will be the same whether or not the pin is configured as RB3 with pull-up enabled or as MCLR.
The leakage current on the nMCLR pin is strongly dependent on the applied voltage level. The specified levels represent
normal operating conditions. Higher leakage may be measured at different input voltages.
