7.2 On-Resistance

The on-resistance of the MUX50x is the ohmic resistance across the source (Sx, SxA, or SxB) and drain (D, DA,

or DB) 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 26. Voltage (V)

and current (ICH) are measured using this setup, and RON is computed as shown in Equation 1:

RON = V / ICH

7.3 Off Leakage

There are two types of leakage currents associated with a switch during the OFF state:

1. Source off-leakage current

2. Drain off-leakage current

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

off. This current is denoted by the symbol IS(OFF).

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

This current is denoted by the symbol ID(OFF).

The setup used to measure both off-leakage currents is shown in Figure 27
