Is the break-before-make time already included in the t_TRANSITION value for the ADG5209, especially at the higher end of the temperature range?
The tTransition value for the ADG5209 includes the break-before-make timing. The transition time is the delay when switching from one channel to another, and the break-before-make time represents the minimum duration when the D (output) side is disconnected from all Sx (inputs).
