4. ESD Ratings

When a statically-charged person or object touches an electrostatic discharge sensitive device, the

electrostatic charge might be drained through sensitive circuitry in the device. If the electrostatic discharge

possesses sufficient energy, damage might occur to the device due to localized overheating.

Note:

(1) All system-level tests are performed using application-specific capacitors connected to the supply pins VCCA and VCCB.

(2) According to the IEC 61000-4-2 standards, a level 4 contact discharge of ±8 kV is considered equivalent to a ±15 kV air

discharge. Air discharge is provided for information only and was not tested.
