These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.

(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 other 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 are with respect to network ground terminal.

(3)

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

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

capacitor discharged directly into each pin.

(1) Maximum power dissipation is a function of TJ(max), θJA and TA. The maximum allowable power dissipation at

any allowable ambient temperature is PD = [TJ(max)-TA] / θJA.

(2) This thermal data is measured with high-K board (4 layer board according to JESD51-7 JEDEC standard).
