[1] H = HIGH voltage level
L = LOW voltage level
h = a HIGH must be present one set-up time before the LOW to HIGH transition of LEAB, LEBA, EAB and EBA
l = a LOW must be present one set-up time before the LOW to HIGH transition of LEAB, LEBA, EAB and EBA
X = don’t care
= LOW to HIGH level transition
NC = no change
Z = high-impedance OFF-state
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 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 SO24 packages: above 70 C the value of Ptot derates linearly with 8 mW/K.
For (T)SSOP24 packages: above 60 C the value of Ptot derates linearly with 5.5 mW/K.
For DHVQFN24 packages: above 60 C the value of Ptot derates linearly with 4.5 mW/K.
