Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. These
ratings are stress specifications only and functional operation of the device at these or any other conditions above those
listed in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions
for extended periods may affect product reliability.
Notes:
1. The input and output negative voltage
ratings may be excluded if the input
and output clamp ratings are observed.
2. This value is limited to 2.5V maximum.
3. The package thermal impedance is
calculated in accordance with
JESD 51.

Guaranteed by design, not 100% tested in production.
Note: Rst and Cn inputs must be helf at valid logic levels (not floating) to ensure proper device operation. The
differential inputs must not be floating unless Rst is low.
