(1)

The maximum frequency is defined with the following conditions: (tr+tf) ≤ 2/3 T Skew ≤ 1/20 T 45% < Duty

cycle < 55%

(2)

The fall and rise times are defined between 90% and 10% and between 10% and 90% of the output waveform,

respectively.

(3)

Value guaranteed by characterization, not 100% tested in production.

(4)

The data is for reference only, and the specific values are related to PCB Layout.
