    MIKROE Analog MUX Click is a Click board™ that switches one of the sixteen inputs to one output. It employs the CD74HC4067, a High-Speed CMOS Logic 16-Channel Analog Multiplexer/Demultiplexer, produced by Texas Instruments. It offers rail-to-rail operation, allowing the input signal to swing up (and down) to the voltage of the power supply, with no distortion. Features such as the low on-resistance and low input current leakage, fast and balanced propagation delay and transition times and break-before-make switching action make this circuit a perfect solution for various switching applications, analog and digital signals.

    Analog MUX Click is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket.

    Analog MUX Click is equipped with the CD74HC4067, a high-speed CMOS logic 16-channel analog multiplexer/demultiplexer, produced by Texas Instruments. It supports 3.3V and 5V power supplies, as well as rail to rail operation, which allows it to be used in a very wide range of different applications. Four control pins are used to switch one of sixteen inputs to a single output. Control pins labeled as S0, S1, S2, and S3 are routed to the mikroBUS™ and can be operated by both 3.3V and 5V MCUs. These pins are routed to RST, PWM, INT, and CS pins of the mikroBUS™ respectively, while the common output pin from the multiplexer is routed to the AN pin on the mikroBUS™.

    The CD74HC4067 IC is digitally controlled analog switch that utilize silicon-gate CMOS technology to achieve operating speeds similar to LSTTL, with the low power consumption of standard CMOS integrated circuits. The mentioned analog multiplexer/demultiplexer control analog voltages that may vary across the voltage supply range.

    The ultra-low leakage current ensures that there is no signal interference from the inputs that are not selected by the S0, S1, S2, and S3 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. Analog MUX click is bidirectional switch as well, thus allowing any analog input to be used as an output and vice-versa. The switches have low “on” resistance and low “off” leakages.

    All of the input channels can be easily connected to the two 9 pole spring action block terminals, without having to use any additional tools, such as screwdrivers.

    More information about the CD74HC4067 can be found in the attached datasheet. However, the Click board™ comes equipped with a library that contains easy to use functions and a usage example that may be used as a reference for the development.

    Analog MUX Click offers a selection between 3.3V and 5V operation, with the onboard SMD jumper, labeled as PWR SEL. This allows both 3.3V and 5V MCUs to be interfaced with this Click board™.
