TMUX7208PWR Typical application Circuitry

TMUX7208PWR

The TMUX7208PWR is a precision, low-on-resistance, 8-channel 1:1 analog multiplexer from Texas Instruments, designed for various applications where multiple analog or digital signals need to be routed to a single output. Its low on-resistance and high signal integrity make it ideal for data acquisition systems, test equipment, and other applications requiring high precision. Here's how you can integrate the TMUX7208PWR into a circuit, focusing on its essential connection aspects:

1. Power Supply Connections: Connect the V_DD pin to your positive power supply, which can range from 2.7 V to 5.5 V, ensuring compatibility with a variety of logic families. Also, connect the V_SS pin to the negative power supply, which can be as low as -5.5 V, providing a wide range for analog signal handling. Ground (GND) should be connected to your system's ground.

2. Signal Connections: The TMUX7208PWR has eight channels, meaning you can connect up to eight different signal lines to the COM (common) ports (COM0 to COM7). These ports are where you input the signals to be multiplexed or demultiplexed, depending on your application.

3. Control Logic: The TMUX7208PWR device uses three digital select inputs (S0, S1, S2) to control the selection of channels. By applying appropriate logic levels to these pins, you can select any one of the eight channels to connect to the respective NO (Normally Open) port. For instance, a logic level "000" at S0 to S2 would connect COM0 to NO0, "001" would connect COM1 to NO1, and so forth.

4. Enable Functionality: The TMUX7208 features an enable pin (EN), which is active low. When EN is driven high, all channels are off, and no connection exists between the COM and NO ports. Driving EN low activates the selected channel, as determined by the S0, S1, and S2 inputs.

5. Decoupling Capacitors: It's advisable to use decoupling capacitors close to the power supply pins (V_DD and V_SS) to minimize power supply noise and ensure stable operation of the multiplexer. This is particularly important in precision applications where signal integrity is critical.

6. Layout Considerations: For optimal performance, especially in high-frequency or sensitive applications, pay careful attention to the PCB layout. Keep the signal paths short and well-separated to minimize crosstalk and noise coupling. Also, ensure that the power supply and ground paths are robust to minimize voltage drops and ground bounce.

By carefully connecting these components and following proper layout practices, you can effectively integrate the TMUX7208PWR into your circuit, leveraging its high-performance switching capabilities for precise signal routing in your application.
