7.1 Absolute Maximum Ratings

Over operating free-air temperature range (unless otherwise noted)(1)(2)
MIN MAX UNIT
Supply voltage (VDD) Absolute minimum/maximum supply voltage –0.5 4 V
Voltage Differential I/O –0.5 4 V
Control pin (SEL) –0.5 VDD + 0.5
Storage temperature, Tstg –65 150 °C
(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any conditions beyond those indicated under Recommended Operating Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) All voltage values, except differential voltages, are with respect to network ground terminal.

7.2 ESD Ratings
