Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5 kresistor between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating. 2. 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 ). This is done for all couples of connected pin combinations while the other pins are floating. 3. Charged device model: all pins and the package are charged together to the specified voltage and then discharged directly to the ground through only one pin. This is done for all pins.
