Parameters Sym Min Typ Max Units Conditions
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.
6: This parameter is established by characterization and not 100% tested.
