All pins

VOUTR, VOUTL vs. AGND

5.

Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a

1.5 k

Ω resistor between two pins of the device. This is done for all couples of connected pin combinations

while the other pins are floating.

6.

Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between

two pins of the device with no external series resistor (internal resistor < 5

Ω). This is done for all couples of

connected pin combinations while the other pins are floating.
