9 Detailed Description

9.1 Overview

The TMUX6111, TMUX6112, and TMUX6113 are 4-channel single-pole/ single-throw (SPDT) switches that

supports dual supplies (±5 V to ±16.5 V) or single supply (10 V to 16.5 V) operation. Each channel of the switch

is turned on or turned off based on the state of its corresponding SELx pin. The Functional Block Diagram

section provides a top-level block diagram of the switches.

9.1.1 On-Resistance

The on-resistance of the TMUX611x 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 1. Voltage (V) and current (ICH) are

measured using this setup, and RON is computed as shown in Equation 1:

RON = V / ICH

9.1.2 Off-Leakage Current

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 2
