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 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 VO > VDDQ.

3. The package thermal impedance is calculated in accordance with JESD 51.
