* 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 configuration, 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 specified lev-
els represent normal operating conditions. Higher leakage current may be measured at different input volt-
ages.
3: Negative current is defined as coming out of 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: PIC17CXX Programming
Specifications (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 specifications may be used.
Note: When using the Table Write for internal programming, the device temperature must be less than 40˚C.
