H = HIGH voltage level;
h = HIGH voltage level one set-up time prior to the HIGH-to-LOW LE transition;
L = LOW voltage level;
l = LOW voltage level one set-up time prior to the HIGH-to-LOW LE transition;
X = don’t care;
Z = high-impedance OFF-state.
The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
For SO20 packages: above 70 C the value of P
For TSSOP20 packages: above 60 C the value of P
