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.

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)

Operation above 4.8V input voltage is not recommended over an extended period of time.

(3)

All voltage values are with respect to network ground terminal.

(4)

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.

(5)

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.
