12Pcs CD74HC4067 16-Channel Analog Digital Multiplexer MUX Breakout Board Module CD74HC4067 CMOS Precise Module Compatible with DIY
- CD74HC4067 board for the very handy 16-Channel Analog/Digital Multiplexer/Demultiplexer, use the CD74HC4067 16-channel analog signal switch.
- 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 want two-way communications,you can add a second board to route your microcontroller's TX line to 16 device's RX 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, perform “break-before-make” switching. The board also breaks out the chip’s “enable” pin, which when driven high, will completely disconnect the common pin (all switches “off”)..
- To control it, connect 4 digital outputs to the chip’s address select pins (S0-S3), and send it the binary address of the channel you want. 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 devi....
