Conditions

These parameters are characterized but not tested.

Data in “Typ” column is at 5V, 25

°C unless otherwise stated. These parameters are for design guidance only

and are not tested.

These parameters are for design guidance only and are not tested, nor characterized.

Note 1: In RC oscillator conguration, the OSC1/CLKIN pin is a Schmitt Trigger input. It is not recommended that the

PIC17CXX 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. The specied levels

represent normal operating conditions. Higher leakage current may be measured at different input voltages.

3: Negative current is dened as coming out of the pin.

4: These specications are for the programming of the on-chip program memory EPROM through the use of the

table write instructions. The complete programming specications can be found in: PIC17CXX Programming

Specications (Literature number DS30139).

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 specications may be used.
