The ● denotes the speciﬁcations which apply over the full operating

temperature range, otherwise speciﬁcations are at TA = 25°C. VCC = 2.7V to 5.5V, unless otherwise noted.

voltage than its input. The magnitude of this offset voltage as a function of

the pull-up resistor and VCC voltage is shown in the Typical Performance

Characteristics section.

Note 5: IPULLUPAC varies with temperature and VCC voltage, as shown in

the Typical Performance Characteristics section.

Note 6: Determined by design, not tested in production.

Note 7: ICC test performed with connection circuitry active.

Note 8: When ﬂoating, the ACC pin can tolerate ±5µA of leakage.

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 speciﬁed.

Note 3: Pulsed less than 5µs.

Note 4: The connection circuitry always regulates the output to a higher
