3 Description

The TMUX6234 is a multi-channel CMOS switch

with low on-resistance. The TMUX6234 contains four

independently controlled SPDT switches with an EN

pin to enable or disable all four channels. The device

supports single supply (4.5 V to 36 V), dual supplies

(±4.5 V to ±18 V), or asymmetric supplies (such

as VDD = 18 V and VSS = –5 V). The TMUX6234

supports bidirectional analog and digital signals on the

source (Sx) and drain (D) pins ranging from VSS to

VDD.

All logic control input pins support logic levels from 1.8

V to VDD, ensuring logic compatibility when operating

with a wide range of logic voltages. Fail-Safe Logic

circuitry allows voltages on the control pins to be

applied before the supply pin, protecting the device

from potential damage.

The TMUX6234 is part of the precision switches and

multiplexers family of devices. These devices have

very low on and off leakage currents and low charge

injection, allowing them to be used in high precision

measurement applications.
