7.3 On-Leakage Current

Source on-leakage current is defined as the leakage current flowing into or out of the source pin when the switch

is on. This current is denoted by the symbol IS(ON).

Drain on-leakage current is defined as the leakage current flowing into or out of the drain pin when the switch is

on. This current is denoted by the symbol ID(ON).

Either the source pin or drain pin is left floating during the measurement. Figure 7-3 shows the circuit used for

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

7.4 Transition Time

Transition time is defined as the time taken by the output of the device to rise or fall 10% after the address signal

has risen or fallen past the logic threshold. The 10% transition measurement is utilized to provide the timing of

the device. System level timing can then account for the time constant added from the load resistance and load

capacitance. Figure 7-4 shows the setup used to measure transition time, denoted by the symbol tTRANSITION.
