Note 14: Voltage Range 5.0 is 5.0V ±0.5V.
Voltage Range 3.3 is 3.3V ±0.3V.
Note 15: Skew is defined as the absolute value of the difference between the actual propagation delay for any two separate outputs of the same device. The speci-
fication applies to any outputs switching in the same direction, either HIGH to LOW (tOSHL) or LOW to HIGH (tOSLH). Parameter guaranteed by design.
