915 Generation 12Pcs CD74HC4067 16-Channel Analog Digital Multiplexer Modul

CD74HC4067 board for the 16-Channel Analog/Digital Multiplexer/Demultiplexer, use the CD74HC4067 16-channel analog signal switch;Analog signal input: C0-C15 16 channels; Analog output: DIG; Channel control: S0-S3
It works with both digital and analog signals (the voltage can't be higher than VCC), and the connections function in either direction.If you two-way communications,you can a second board to route your microcontroller's TX line to 16 device's lines. By using multiple boards, you can create similar arrangements for I2C,SPI,etc.
The internal switches are bidirectional, support voltages between ground and VCC, have low "on" resistance and low "off" leakage, and to prevent crosstalk, "break--make" switching. The board also breaks out the chip's "enable" pin, which when high, will completely disconnect the common pin (all switches "off").
To control it, digital outputs to the chip's address select pins (S0-S3), and send it the binary address of the channel you . This allows you to connect up to 16 sensors to your system using only 5 pins.
Since the mux/demux also works with digital signals, you can use it to pipe TTL level serial data to or from multiple devices. For example, you could use it to connect the TX pins of 16 devices to one pin on your microcontroller. You can then select any one of those 16 devices to listen to. Material:plastic
