Notes:

1. The input and output negative voltage

ratings may be excluded if the input

and output clamp ratings are observed.

2. This current will flow only when the

output is in the high state level

V0 >VDDQ.

3. The package thermal impedance is

calculated in accordance with

JESD 51.

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.
