74LVC125A
Quad buffer/line driver with 5 V tolerant input/outputs; 3-state
7. Limiting values
[1] The minimum input voltage ratings may be exceeded if the input current ratings are observed.
[2] The output voltage ratings may be exceeded if the output current ratings are observed.
[3] For SO14 packages: above 70 C derate linearly with 8 mW/K.
For (T)SSOP14 packages: above 60 C derate linearly with 5.5 mW/K.
For DHVQFN14 packages: above 60 C derate linearly with 4.5 mW/K.
