Note:

Stresses greater than those listed under MAXIMUM

RATINGS may cause permanent damage to the device.

This is a stress rating only and functional operation of the

device at these or any other conditions above those

indicated in the operational sections of this specification

is not implied. Exposure to absolute maximum rating

conditions for extended periods may affect reliability.

Notes:

1. The input and output negative-voltage ratings maybe exceeded if the input and

outputclamp-current ratings are observed.

2. This value is limited to 4.6V maximum.
