Functional description

[1]

H = HIGH voltage level;

L = LOW voltage level.

7.

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

[3]

For SO14 packages: above 70

°C derate linearly with 8 mW/K.

For SSOP14 and TSSOP14 packages: above 60

°C derate linearly with 5.5 mW/K.

For DHVQFN14 packages: above 60

°C derate linearly with 4.5 mW/K.
