Note 1: All pins withstand 500V based on Human Body Model, JEDEC JESD22-A114-D.
Note 2: Applies to all input supply voltages. Stresses above those listed under “Absolute Maximum Ratings” may cause
permanent damage to the device. These are stress ratings only and functional operation of the devices at those or any
other conditions above those indicated in the Recommended Operating Conditions of this specification is NOT implied.
Also note that exposure to maximum rating conditions for extended periods of time may affect device reliability.
Note 3: Differential input voltage amplitude is peak to peak value.
