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.

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for

which the device is intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test

conditions, see the Electrical Characteristics Tables.

(2)

When the input voltage (VIN) at any pin exceeds power supplies (VIN < GND or VIN > VS ), the current at that pin must not exceed

5mA, and the voltage (VIN) has to be within the Absolute Maximum Rating for that pin. The 20mA package input current rating limits the

number of pins that can safely exceed the power supplies with current flow to four pins.
