Note
1:
Trip point is ±1.5% from typical value.
2:
Trip point is ±2.5% from typical value.
3:
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).
This specification DOES NOT allow a continuous 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 100 sec. Current into the
V
OUT
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 information, please refer to Figure 2-28.

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