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 other conditions beyond those indicated under recommended operating

conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods my affect device reliability.

(2)

All voltages are with respect to network ground terminal.

(3)

Limit the junction temperature to 105°C for continuous operation at maximum output power.

(4)

Limit the junction temperature to 125°C for 5% duty cycle operation.

(5)

In applications where high power dissipation and/or poor package thermal resistance is present, the maximum ambient temperature may

recommended to operate the device with a maximum junction temperature of 105°C.

(6)

The human body model is a 100-pF capacitor discharged through a 1.5-k

Ω resistor into each pin. The machine model is a 200-pF

capacitor discharged directly into each pin.
