ABSOLUTE MAXIMUM RATINGS
WARNING:Operations at or beyond these limits may result in permanent damage to the device.
Notes: 1. Excluding RTIP, RRING, which must stay within -6V to (RV+) + 0.3V.
RECOMMENDED OPERATING CONDITIONS
Notes: 3. TV+ must not exceed RV+ by more than 0.3V.
DIGITAL CHARACTERISTICS
Notes: 6. In Extended Hardware Mode, pins 17 and 18 are digital inputs. In Host Mode, pin 23 is
