nThis is a breakout board for the very handy 16-Channel Analog Multiplexer
nThis chip is like a rotary switch – it internally routes the common pin
n(COM in the schematic, SIG on the board)to one of 16 channel pins (CHANxx).
nIt works with both digital and analogue signals (the voltage can’t be higher than VCC),
nand the connections function in either direction.
nTo control it, connect 4 digital outputs to the chip’s address select pins (S0-S3),
nand send it the binary address of the channel you want (see the datasheet for details).
nThis allows you to connect up to 16 sensors to your system using only 5 pins!
nSince the mux/demux also works with digital signals,
nyou can use it to pipe TTL-level serial data to or from multiple devices.
nFor example, you could use it to connect the TX pins of 16 devices to one RX pin on your microcontroller.
nYou can then select any one of those 16 devices to listen to.
nIf you want two-way communications, you can add a second board to route
nyour microcontroller’s TX line to 16 device’s RX lines.
nBy using multiple boards, you can create similar arrangements for I2C, SPI, etc.
nThe internal switches are bidirectional, support voltages between ground and VCC,
nhave low “on” resistance and low “off” leakage, and to prevent crosstalk, perform “break-before-make” switching.
nThe board also breaks out the chip’s “enable” pin, which when driven high,
nwill completely disconnect the common pin (all switches “off”).
