Texas Instruments TMUX612x 36V Dual SPST Switches
Texas Instruments TMUX612x 36V Switches offer two independently selectable single-pole, single-throw (SPST) switches. The TMUX612x works well with dual supplies (±5V to ±16.5V), a single supply (10V to 16.5V), or asymmetric supplies. All digital inputs have transistor-transistor logic (TTL) compatible thresholds. This feature ensures both TTL and CMOS logic compatibility.
The devices are turned on with Logic 1 on the digital control inputs in the TMUX6121, and Logic 0 is required to turn on switches in the TMUX6122. The TMUX6123 has one switch with similar digital control logic to the TMUX6121, while the logic is inverted on the other switch. The TMUX6123 provides break-before-make switching, allowing the device to be used in the cross-point switching application. The Texas Instruments TMUX612x has a very low leakage current and low charge injection, enabling usage in high-precision measurement applications. A low supply current of 16µA makes the TMUX612x Switches ideal for portable applications.
