Texas Instruments TMUX6234 2:1 4-Channel Precision Switch
Texas Instruments TMUX6234 2:1 4-Channel Precision Switch 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 (4.5V to 36V), dual supplies (±4.5V to ±18V), or asymmetric supplies (such as VDD = 18V and VSS = –5V). 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 1.8V 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 Texas Instruments 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.
