Analog Multiplexer designed for high-precision measurement applications

The Texas Instruments TMUX6104 is a modern CMOS analog MUX that offers 4:1 single-ended multiplexing. The devices work well with dual supplies (±5V to ±16.5V), a single supply (10V to 16.5V), or unsymmetric supplies (such as V_DD = 12V, V_SS = –5V). All digital inputs have transistor-transistor logic (TTL) compatible thresholds, ensuring both TTL and CMOS logic compatibility. The device multiplexes one of four inputs (Sx) to a common output (D), depending on the status of the address pins (A0/A1) and the enable pin (EN). Each switch conducts equally well in both directions in the ON position and supports input signal range up to the supplies. In the OFF condition, signal levels up to the supplies are blocked. All switches exhibit break-before-make (BBM) switching action. The device is part of the company's Precision Switches and Multiplexers family. The family of devices have very low leakage current and charge injection, allowing them to be used in high-precision measurement applications. Low supply current of 17 µA enables the device’s usage in portable applications.
