ELECTRICAL CHARACTERISTICS
 
The ?/SPAN> denotes the speci cations which apply over the full operating
temperature range, otherwise speci cations are at T
A
 = 25癈. V
CC
 = 2.7V to 5.5V, unless otherwise noted.
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: All currents into pins are positive; all voltages are referenced to 
GND unless otherwise speci ed.
Note 3: Pulsed less than 5?/SPAN>s.
Note 4: The connection circuitry always regulates the 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 5: I
PULLUPAC
 varies with temperature and V
CC
 voltage, as shown in
the Typical Performance Characteristics section.
Note 6: Guaranteed  by design, not tested in production.
Note 7: I
CC
 test performed with connection circuitry active.
