Absolute Maximum Ratings

The ABSOLUTE MAXIMUM ratings below are stress ratings only. Operation at or beyond these maximum ratings can cause permanent damage to device.

Electrical specifications do not apply when operating beyond rated operating conditions. Operating beyond rated operating conditions for extended period of

time may affect device reliability. All voltages are specified relative to SGND unless otherwise noted. Positive pin current represents current flowing

out of the pin.
