Table 8: AC Electrical Characteristics (CL = 50 pF, RL = 500 Ω, Input tr = tf = 3ns)

1) Skew is defined as the absolute value of the difference between the actual propagation delay for any two outputs of the same device switch-

ing in the same direction, either HIGH or LOW (tOSLH = |tPLHm - tPLHn|, tOSHL = |tPHLm - tPHLn|)

2) Parameter guaranteed by design

(*) Voltage range is 3.3V
