# Title: MUX Click Board™ ## Description: How Does The MUX Click Board™ Work? The MUX Click Board™ is equipped with the MUX509, a precise analog multiplexing IC, produced by Texas Instruments. The MUX509 can be used with a wide range of power supplies. It can handle both dual and single power supplies, as well as the symmetrical and non-symmetrical ones. This allows it to be used in a very wide range of different applications. Another property of the MUX509 IC is that it has dual inputs and dual output. Three control pins are used to switch one of four input pairs to a single output pair. Control pins labelled as A0 and A1 are routed to the mikroBUS™ and can be operated by both 3.3V and 5V MCUs. The third control pin is labelled as EN pin, used to enable the output when is set to a HIGH logic level (it is active HIGH). A0 and A1 pins are routed to RST and PWM pins of the mikroBUS™ respectively, while the EN pin is routed to the CS pin on the mikroBUS™. The MUX509 IC is targeted towards working with differential signals, rather than working with the single-ended inputs. Each input is composed of two pins: SNA, and SNB, where N represents the channel number in the range from 1 to 4. When a specific channel is selected (N), both the SNA and SNB pins of that channel will be routed to the DA and DB output pins, respectively. For the improved stability, each signal pair is equipped with the 100nF parallel capacitor and 100Ω series resistance. The input and the output signal pins are routed to the standard 2.54mm pitch 2x5 pins header on the Click board™. The ultra-low leakage current ensures that there is no signal interference from the inputs that are not selected by the A0 and A1 pins. A low crosstalk also ensures that the signal on one channel remains clean of interferences caused by other channels. To prevent any two inputs to be switched at the output at the same time, a break-before-make switching action is utilized. This ensures a reliable operation of the IC and the Click board™ itself. The MUX Click Board™ does not use the power from the mikroBUS™ power rails, except for the LED indicator. Instead, a three-pole screw terminal is used to connect an external power supply. Having in mind the minimum input voltage of 10V or ±5V, a power supply should be connected to this terminal before operating the Click board™. Depending on the type of the used power supply (single supply or symmetrical/dual supply), it should be connected to the power supply input terminal, accordingly: GND is the reference ground connection, VSS is the negative voltage connection terminal (GND if a single power supply is used), and VDD is the positive voltage connection terminal. The input and output signals can be connected via the 2x5 pins header. As mentioned before, the MUX509 IC supports rail-to-rail operation, supporting input and output signals that range from VSS (or GND) up to VDD. Independent power supply input allows the user to work with a wide range of signal amplitudes, depending on the application requirements, as long as the power supply stays within the limits. More information about the MUX509 can be found in the attached datasheet.

Additional Notes and Information

Depending on the development board you are using, you may needs a USB UART click, USB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.

MIKROSDK

The MUX Click Board™ is supported with mikroSDK - MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant click board demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
