VCC to GND .............................................. –0.3V to 6.5V

VPCA/B Voltage to GND ............................ –0.3V to 3.2V

PCTL Voltage to GND ................. – 0.3V to (VCC + 0.3V)

RF Voltage to GND ............................ (VCC – 2.6V) to 7V

BSEL, SHDN Voltage to GND ...... – 0.3V to (VCC + 0.3V)

The q denotes specifications which apply over the full operating

temperature range, otherwise specifications are at TA = 25°C. VCC = 3.6V, SHDN = HI, unless otherwise noted.
