Short-circuits can cause excessive heating and destructive dissipation. 2. Rth are typical values. 3. Human body model: 100pF discharged through a 1.5kΩ resistor between two pins of the device, done for all couples of pin combinations with other pins floating. 4. Machine model: a 200pF cap is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5Ω). Done for all couples of pin combinations with other pins floating. 5. Charged device model: all pins plus package are charged together to the specified voltage and then discharged directly to the ground. http://www.hgsemi.com.cn 3 2018 AUG OP07C 3 Electrical characteristics Table 2.
