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, 5.25 V, LEN2/1/0=1/1/1, a 100 Ω load and a 1:1.15 transformer.

Notes: 6. 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 digital output.

7. This specification guarantees TTL compatibility (VOH = 2.4V @ IOUT = -40µA).

8. Output drivers will drive CMOS logic levels into a CMOS load.

9. As an alternative to supplying a 2.3-to-2.7V input, this pin may be left floating.
