TECNOULAB 5pcs CD74HC4067 16 Channel Digital Analog Multiplexer Breakout Board Module

【CD74HC4067】CD74HC4067 16 Channel Analog Digital Multiplexer Breakout Board Module 【Compact Design】This is an output board for the very handy 16-channel analog/digital multiplexer/demultiplexer CD74HC4067. -This chip is like a rotary switch: it internally routes the common pin (COM on the schematic, SIG on the board) to one of the 16 channel pins (CHANxx). 【High Performance】-To control it, connect 4 digital outputs to the chip's address selection pins (S0-S3) and send them to the binary address of the desired channel (see datasheet for details). -This allows you to connect up to 16 sensors to your system using just 5 pins! 【Compatibility】Since the mux/demux also works with digital signals, you can use it to channel 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 RX pin on your microcontroller
