(2)All voltage values except the differential voltage are with respect to the network ground terminal. (3)The voltage on either input must never exceed VCC + 0.3 V nor 16 V. (4)Short circuits can cause excessive heating and destructive dissipation. Values are typical. (5)Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5 kΩ resistor between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating.
