Data in “Typ” column is at 5V, 25
°C unless otherwise stated. These parameters are for design guidance only and are not tested.
Note 1: In EXTRC oscillator configuration, the OSC1/CLKIN pin is a Schmitt Trigger input. It is not recommended that the
MCV14A be driven with external clock in RC mode.
2: Negative current is defined as coming out of the pin.
3: This spec. applies to RB3/MCLR configured as RB3 with internal pull-up disabled.
4: 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.
