Notes:

(1)All voltage values, except differential voltage, are with respect to network ground terminal.

(2)The differential voltage is the non-inverting input terminal with respect to the inverting input terminal.

(3)VCC - Vin must not exceed 6 V, Vin must not exceed 6 V.

(4)Input current must be limited by a resistor in series with the inputs.

(5)Rth are typical values.

(6)Short-circuits can cause excessive heating and destructive dissipation.

(7)Human body model: 100 pF discharged through a 1.5 kΩ resistor between two pins of the device, done for all couples of pin

combinations with other pins floating.

(8)Machine model: a 200 pF cap is charged to the specified voltage, then discharged directly between two pins of the device with

no external series resistor (internal resistor < 5

Ω), done for all couples of pin combinations with other pins floating.
