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 Table 2. 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.
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
thermal impedance, the junction temperature would be 123.4 °C, which is within the 125 °C maximum rating.
