8 Parameter Measurement Information

8.1 Truth Tables

Table 8-1, Table 8-2, and Table 8-3 show the truth tables for the TMUX7411F, TMUX7412F, and TMUX7413F,

respectively. Each switch is independently controlled by its own select pin.

8.2 On-Resistance

The on-resistance of the TMUX7411F, TMUX7412F, and TMUX7413F 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. Figure 8-1 shows the measurement setup used to measure RON.

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.
