1. Electrical Specifications
Unless noted otherwise, specifications apply over the operating temperature range with VDD = +3.3 V, and
VEE = –48 V relative to GND.
VDD pins should be electrically shorted. AGND pins, DGND, GND12, and GND34 should be electrically shorted
("GND"). VEE, VEE1, VEE2, VEE3, and VEE4 should be electrically shorted ("VEE").
VPort for any port is measured from GND to the respective VOUTn.

Notes:
1. Functional operation should be restricted to those conditions specified in the Recommended Operating Conditions
2. See IEEE Std 802.3-2005, clause 33.4 for a description of surge events.
3. If all ports are on with 600 mA load, the power dissipation is <1.2 W. At 85 °C ambient with the expected 32 °C/W
section of this data sheet. Functional operation or specification compliance is not implied at these conditions. Stresses
beyond those listed in Absolute Maximum Ratings may cause permanent damage to the device.
