Note 1:

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. DC and

AC electrical specifications do not apply when operating the device beyond its rated operating conditions.

Note 2:

When the input voltage (Vi) at any pin exceeds the power supply (Vi<GND or Vi>+Vs) the current at

that pin should be limited to 5mA. The 20mA maximum package input current rating limits the number of pins

that can safely exceed the power supplies with an input current of 5mA to four.

Note 3:

Human body model, 100pF discharged through a 1.5K Ω resistor. Machine model, 200pF

discharged directly into each pin.

Note 4:
