This chip is like a rotary switch - it internally routes the common pin (COM in the circuit diagram, SIG on the board) to one of 16 channel pins (CHANxx). Works with digital and analog signals (voltage cannot be higher than VCC) and connections work in both directions. To control it, connect 4 digital outputs to the address selection pins (S0 - S3) of the chip and send it the binary address of the desired channel (see the datasheet for details). This allows you to connect up to 16 sensors to your system using just 5 pins. Since the multiplexer\/demultiplexer also works with digital signals, you can use it to transmit serial TTL data from or to multiple devices. For example, you could use it to connect the TX pins of 16 devices to one RX pin on your microcontroller. You can then select one of these 16 devices to listen to. If you want bi-directional communication, you can add a second card to route your microcontroller's TX line to 16 RX lines of the device. If you use multiple modules, you can create similar arrangements for I2C, SPI, etc. The internal switches are bidirectional, support voltages between ground and VCC switches, have low \"on\" resistance and low \"off\" loss, and to prevent heterodyne they perform \"before power-on\" switching. The board also breaks out the chip's \"enable\" pin, which, when performing high power, completely disconnects the common pin (all switches \"off\"). Features: 1. 2V to 6V operation. 2., “On” resistance: 70 ohms at 4.5 V. 3. 6 Ns “break” before switching on at 4.5 V. 4., Wide operating voltage range: -55 to 125 °C.
