ELECTRICAL CHARACTERISTICS
Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: The greater of V1, V2 is the internal supply voltage (VCC).
Note 3: All currents into pins are positive; all voltages are referenced to
GND unless otherwise noted.
Note 4: For reset thresholds test conditions refer to the voltage threshold
programming table in the Applications Information section.
Note 5: The output pins RST and RST have an internal pull-up to VCC of
typically –6μA. However, an external pull-up resistor may be used when
faster rise time is required or for VOH voltages greater than VCC.
Note 6: The input current to the three-state input pins are the pull-up
and the pull-down current when the pins are either set to V1 or GND
respectively. In the open state, the maximum leakage current to V1 or GND
permissible is 10μA.
