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.
