WARNING:Operations at or beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.
Notes:
1. Excluding RTIP, RRING, which must stay within -6V to (RV+) + 0.3V.
2. Transient currents of up to 100 mA will not cause SCR latch-up. Also TTIP, TRING, TV+ and TGND
can withstand a continuous current of 100 mA.

Notes:
3. TV+ must not exceed RV+ by more than 0.3V.
4. Power consumption while driving line load over operating temperature range. Includes IC and load.
Digital input levels are within 10% of the supply rails and digital outputs are driving a 50 pF
capacitive 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.

Notes:
7. In Extended Hardware Mode, pins 17 and 18 are digital inputs. In Host Mode, pin 23 is
an open drain output and pin 25 is a tristate output.
8. This specification guarantees TTL compatibility (V

9. Output drivers will drive CMOS logic levels into a CMOS load.
10. As an alternative to supplying a 2.3-to-2.7V input, this pin may be left floating.
