Fuhjythy 10Pcs 16CH Analogue Multiplexer Module 74HC4067 CD74HC4067 Precise Module Digital Multiplexer MUX Breakout Board

This is a very convenient 16 channel CD74HC4067 analog/digital multiplexer/demultiplexer. Because the multiplexer can also process digital signals, you can use it to transfer TTL-level serial data to multiple devices through pipe or transfer from multiple devices. Drive it to a high level, and it completely disconnect the common pins (all switches are disconnected). It is suitable for digital and analog signals (voltage cannot be higher than VCC) and can be connected in either direction. To control this, please connect the four digital outputs to the address selection pin of the chip (SO-S3) and send it the binary address of the desired channel. The internal switch is bidirectional, with a low on resistance and off leakage, and to prevent talk, please turn off the switch first and then on.
