voltage, as shown in
the Typical Performance Characteristics section.
Note 3:
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 pullup resistor and V
CC
voltage is shown in the Typical Performance
Characteristics section.
