8.4 On-Leakage Current

On-leakage current is defined as the leakage current that flows into or out of the drain pin when the switch is in

the on state. The source pin is left floating during the measurement. Figure 28 shows the circuit used for

measuring the on-leakage current, denoted by ID(ON).

8.5 Transition Time

Transition time is defined as the time taken by the output of the MUX50x to rise or fall to 90% of the transition

after the digital address signal has fallen or risen to the 50% of the transition. Figure 29 shows the setup used to

measure transition time, denoted by the symbol tt.
