| time interval required for the leading edge of a waveform to change between two defined levels|
Figure 17 – Characteristics of an output waveform
Note 1 to entry: These levels may be two logic levels VOL and VOH or 10 % to 90 % of its maximum amplitude (VHI – VLO), or any other ratio defined in the detail specification
VOL is the low level output voltage
VOH is the high level output voltage
VHI is the upper flat voltage of the pulse waveform
VLO is the low flat voltage of the pulse waveform.
