Functional description

7.1 Function table

[1]

H = HIGH voltage level;

L = LOW voltage level;

X = don’t care;

Z = high-impedance OFF-state.

8.

Limiting values

[1]

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

are observed.

[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.
