7 Parameter Measurement Information
7.1 On-Resistance
The TMUX7462F's on-resistance is the ohmic resistance across the source (Sx) and drain (Dx) pins of the
device. The on-resistance varies with input voltage and supply voltage. The symbol RON is used to denote
on-resistance. The measurement setup used to measure RON is shown in Figure 7-1. ΔRON represents the
difference between the RON of any two channels, while RON_FLAT denotes the flatness that is defined as the
difference between the maximum and minimum value of on-resistance measured over the specified analog
signal range.

7.2 On-Leakage Current
Source on-leakage current (IS(ON)) and drain on-leakage current (ID(ON)) denotes 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 7-2 shows the circuit used for measuring the on-leakage currents.
