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 connection circuitry always regulates its output to a higher
voltage than its input. The magnitude of this offset voltage as a function of
the pull-up resistor and V
CC
voltage is shown in the Typical Performance
Characteristics section.
Note 3: Determined by design, not tested in production.
