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.
