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: All currents into pins are positive. All voltages are referenced to

GND unless otherwise speciﬁed.

Note 3: Thermal characteristics are determined with exposed pad soldered

to GND plane. If the exposed pad is left open, thermal characteristics can

be drastically different.

•

The ● denotes the speciﬁcations which apply over the full operating

temperature range, otherwise speciﬁcations are at TA = 25°C. VCC = 3.3V, unless otherwise noted.

Note 4: The rise time of an I2C bus line is calculated from VIL(MAX) to

VIH(MIN) or 0.9V to 2.1V (with VCC = 3V). This parameter is guaranteed by

design and not tested. With a minimum boosted pull-up current of 2.5mA:

Rise Time = (2.1V – 0.9V) • 400pF/2.5mA = 0.19μs.

Note 5: Determined by design, not tested in production.
