8.3 On-Leakage Current

Source on-leakage current (IS(ON)) and drain on-leakage current (ID(ON)) denote the channel leakage currents

when the switch is in the on state. IS(ON) is measured with the drain floating, while ID(ON) is measured with the

source floating. Figure 8-3 shows the circuit used for measuring the on-leakage currents.

8.4 Device Turn-On and Turn-Off Time

Turn-on time (tON) is defined as the time taken by the output of the TMUX8211, TMUX8212, and TMUX8213

to rise to a 90% final value after the SELx signal has risen (for NC switches) or fallen (for NO switches) to a

50% final value. Turn off time (tOFF) is defined as the time taken by the output of the TMUX8211, TMUX8212,

and TMUX8213 to fall to a 10% initial value after the SELx signal has fallen (for NC switches) or risen (for NO

switches) to a 50% initial value. Figure 8-4 shows the setup used to measure tON and tOFF.
