parameters are referenced to a specific voltage level which specifies when the device
output is no longer driving
(DQ). Figure 80 (page 162) shows a method to calculate the point when the device is no
longer driving
ing the signal at two different voltages. The actual voltage measurement points are not
critical as long as the calculation is consistent. The parameters
