† Notice: Stresses above those listed under “Maximum

Ratings” may cause permanent damage to the device. This is

a 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.

Exposure to maximum rating conditions for extended periods

may affect device reliability.

Trip point is ±1.5% from typical value.

Trip point is ±2.5% from typical value.

RST output is forced low. There is a current through the internal pull-up resistor.

This includes the current through the internal pull-up resistor and the reset power-up timer.

This specification allows this device to be used in PICmicro® microcontroller applications that require In-Circuit Serial

Programming™ (ICSP™) (see device-specific programming specifications for voltage requirements). This specification

DOES NOT allow a continuos high voltage to be present on the open-drain output pin (VOUT). The total time that the

VOUT pin can be above the maximum device operational voltage (5.5V) is 100s. Current into the VOUT pin should be

limited to 2 mA and it is recommended that the device operational temperature be maintained between 0°C to 70°C

(+25°C preferred). For additional information, please refer to Figure 2-33.

This parameter is established by characterization and not 100% tested.
