8.7 Turn-On and Turn-Off Time
Turn-on time is defined as the time taken by the output of the MUX50x to rise to a 90% final value after the
enable signal has risen to a 50% final value. Figure 31 shows the setup used to measure turn-on time. Turn-on
time is denoted by the symbol t_ON.
Turn-off time is defined as the time taken by the output of the MUX50x to fall to a 10% initial value after the
enable signal has fallen to a 50% initial value. Figure 31 shows the setup used to measure turn-off time. Turn-off
