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 device pins are positive; all currents out of
the device pins are negative; all voltages are referenced to GND unless
otherwise specified.
Typical Performance Characteristics Specifications are at TA = 25°C. VCC = 3.3V,
unless otherwise noted.
