† 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.

Note 1: Trip point is ±1.5% from typical value.
2: Trip point is ±2.5% from typical value.
3: RST
output is forced low. There is a current through the internal pull-up resistor.
4: This includes the current through the internal pull-up resistor and the reset power-up timer.
5: This specification allows this device to be used in PIC
®
microcontroller applications that require In-Circuit Serial Pro-
gramming™ (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 (V
OUT
). The total time that the
V
OUT
pin can be above the maximum device operational voltage (5.5V) is 100s. Current into the V
OUT
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.
