The q denotes specifications which apply over the full operating
temperature range.
Note 1: Absolute Maximum Ratings are those values beyond which the
safety of the device cannot be guaranteed. Recommended: VDD = 5V ±5%.
Note 2: All currents into the device pins are positive; all currents out of the
device pins are negative.
Note 3: All typicals are given for VDD = 5V, TA = 25°C.
Note 4: Guaranteed by design, but not tested.
Note 5: Worst-case tPLH – tPHL skew for a single receiver in a package
over the full operating temperature range.
Note 6: Maximum difference between any two tPLH or tPHL transitions in a
single package over the full operating temperature range.
