Sobre este producto

How it Works: This is a breakout board for the CD74HC4067, a useful 16-channel analog/digital multiplexer/demultiplexer. The chip is similar to a rotary switch, it internally routes a common pin (COM in the schematic, SIG on the board) to one of the 16 channel pins (CHANxx)
How to Use: Connect the 4 digital outputs to the address select pins (S0-S3) of the chip and send the binary address of the desired channel. This way you can connect up to 16 sensors to your system with only 5 pins
Bidirectional Communication: If you need bidirectional communication, you can add a second board to connect the TX line of the microcontroller to the RX lines of the 16 devices. By using multiple boards, you can create similar connections for interfaces such as I2C, SPI, etc
Signal Type: The analog multiplexer supports digital and analog signals (voltage cannot be higher than VCC), and the connection works properly in both directions. Since the multiplexer/demultiplexer also supports digital signals, you can use it to transmit TTL-level serial data to multiple devices or receive data from multiple devices
Switching Method: The internal switches are bidirectional, support voltages between ground and VCC, have low on-resistance and low off-leakage, and use a "break before make" switching method to prevent crosstalk. The board also brings out the chip's "enable" pin, which, when driven high, completely disconnects the common pin (all switches are "off")
