Table 11: AC Electrical Characteristics

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

3) To add 2.5ns at tPLH, tPHL max propagation delay time Bn to An at VCCB=1.8±0.15V; VCCA=2.8±0.1V; RL=500Ω, when CL=60 pF
