Functional description

[1]

H = HIGH voltage level; L = LOW voltage level; X = don’t care; Z = high-impedance OFF-state

7.

Limiting values

[1]

Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the

device at these or any other conditions beyond indicated under Section 8 “Recommended operating conditions” is not implied. Exposure

to absolute-maximum-rated conditions for extended periods may affect device reliability.

[2]

The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction

temperatures which are detrimental to reliability.

[3]

The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.
