† Data in “Typ” column is at 5V, 25C unless otherwise stated.
Note 1: In RC oscillator configuration, the OSC1/CLKIN pin is a Schmitt Trigger input. It is not recommended that the
PIC17CXXX devices be driven with external clock in RC mode.
2: The leakage current on the MCLR pin is strongly dependent on the applied voltage level. Higher leakage
current may be measured at different input voltages.
3: Negative current is defined as current sourced by the pin.
4: These specifications are for the programming of the on-chip program memory EPROM through the use of the
table write instructions. The complete programming specifications can be found in: PIC17C7XX Programming
Specifications (Literature number DS TBD).
5: The MCLR
/VPP pin may be kept in this range at times other than programming, but is not recommended.
6: For TTL buffers, the better of the two specifications may be used.
