Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. The l denotes specifications that apply over the full operating temperature range, otherwise specifications are at TA = 25°C, VCC = 7V, DVCC = 3.3V unless otherwise noted (Note 2). Note 2. All currents into pins are positive; all voltages are referenced to GND unless otherwise noted.
