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 performance capability of a high-performance integrated circuit in conjunction with its thermal

environment can create junction temperatures which are detrimental to reliability. The maximum junction

temperature of this integrated circuit should not exceed 150

°C.

[2]

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

[3]

For (T)SSOP48 packages: above 60
