The TMUX6104, developed by Texas Instruments, is a modern complementary metal-oxide semiconductor (CMOS) analog multiplexer designed for precision applications in the industrial sector. It offers a 4:1 single-ended multiplexing capability, making it suitable for various signal routing needs.
This device is compatible with dual supplies ranging from ±5 V to ±16.5 V, a single supply between 10 V and 16.5 V, or unsymmetric supplies like VDD = 12 V and VSS = -5 V. All digital inputs are equipped with transistor-transistor logic (TTL) compatible thresholds, ensuring compatibility with both TTL and CMOS logic systems.
The TMUX6104 allows the selection of one of four inputs (Sx) to be routed to a common output (D), depending on the address pins (A0/A1) and the enable pin (EN) status. In the ON position, each switch conducts equally well in both directions and supports input signal ranges up to the supply voltages. When in the OFF condition, signal levels up to the supplies are blocked. Additionally, all switches exhibit break-before-make (BBM) switching action, ensuring smooth transitions between different input signals.
One of the key features of the TMUX6104 is its ultra-low leakage current and charge injection characteristics, making it highly suitable for high-precision measurement applications. This device also offers a low supply current of 17 µA, making it ideal for portable applications where power consumption is a concern.
In summary, the Texas Instruments TMUX6104 is a versatile analog multiplexer that combines low capacitance, low leakage current, and precision performance. With its wide supply voltage range and compatibility with different logic systems, it is an excellent choice for industrial applications where signal routing and accuracy are critical. Its ultra-low leakage current and low power consumption also make it suitable for portable measurement devices.
