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: 7. In Extended Hardware Mode, pins 17 and 18 are digital inputs. In Host Mode, pin 23 is

10. As an alternative to supplying a 2.3-to-2.7V input, this pin may be left floating.
2. Transient currents of up to 100 mA will not cause SCR latch-up. Also TTIP, TRING, TV+ and TGND
4. Power consumption while driving line load over operating temperature range. Includes IC and load.
5. Assumes 100% ones density and maximum line length at 5.25V.
6. Assumes 50% ones density and 300ft. line length at 5.0V.
8. This specification guarantees TTL compatibility (V
