Notice:
Stresses above those listed under “Maximum Rat-

stress rating only and functional operation of the device at
those or any other conditions above those indicated in the
operational listings of this specification is not implied. Expo-
sure to maximum rating conditions for extended periods may
affect device reliability.

Note 1:
Trip point is ±1.5% from typical value.
Trip point is ±2.5% from typical value.
Hysterysis is minimum = 1%, max = 6% at +25°C.
This specification allows this device to be used in PICmicro
microcontroller applications that require the
In-Circuit Serial Programming (ICSP) feature (see device-specific programming specifications for
voltage requirements). The total time that the RST pin can be above the maximum device operational volt-
age (5.5V) is 100s. Current into the RST pin should be limited to 2 mA. It is recommended that the device
operational temperature be maintained between 0°C to +70°C (+25°C preferred). For additional informa-
tion, refer to Figure 2-35.
This parameter is established by characterization and is not 100% tested.
Custom ordered voltage trip point; minimum order volume requirement. Information available upon request.
