SWITCHI G TI E CHARACTERISTICS

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.
