[1] H = HIGH voltage level;
h = HIGH voltage level one set-up time prior to the LOW-to-HIGH clock transition;
L = LOW voltage level;
l = LOW voltage level one set-up time prior to the LOW-to-HIGH clock transition;
= LOW-to-HIGH transition;
X = don’t care;
q = lower case letter indicates the state of the referenced input one set-up time prior to the LOW-to-HIGH transition.
7. Limiting values
Table 4. Limiting values
In accordance with the Absolute Maximum Rating System (IEC 60134). Voltages are referenced to GND (ground = 0 V).

[1] The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
[2] For SO14 packages: above 70 C the value of Ptot derates linearly at 8 mW/K.
For TSSOP14 packages: above 60 C the value of Ptot derates linearly at 5.5 mW/K.
For DHVQFN14 packages: above 60 C the value of Ptot derates linearly at 4.5 mW/K.
