These are stress ratings only. Operation outside the absolute maximum ratings may cause device failure.
Operation at the absolute maximum rating for extended periods may reduce device reliability.
ESD Susceptibility
Rating Unit
Human Body Model 500 V
Charged Device Model >1000 V
Machine Model <100 V
Semiconductor devices are ESD sensitive and may be damaged by exposure to ESD events. Suitable ESD precautions should be taken when handling and
transporting these devices.
The human body model is a 100pF capacitor discharge through a 1.5k
Ω resistor pin. The machine model is a 200pF capacitor discharged directly into each pin.
