Description:

1.Use the CD74HC4067 16-channel analog signal switch;Analog signal input: C0-C15 16 channels.

2.Analog output: DIG;Channel control: S0-S3

3.This is a breakout board for the very handy 16-Channel Analog / Digital Multiplexer / CD74HC4067.

4.This chip is like a rotary switch – it internally routes the common pin (COM in the schematic, SIG on the board) to one of 16 channel pins . It works with both digital and analog signals (the voltage can’t be higher than VCC), and the connections function in either direction.

5.If you want two-way communications, you can add a second board to route your micro controller’s TX line to 16 device’s RX lines.

6.By using multiple boards, you can create similar arrangements for I2C, SPI, etc.

7.The internal switches are bidirectional, support voltages between ground and VCC, have low “on” resistance and low “off” leakage, and to prevent crosstalk, perform “break-before-make” switching. The board also breaks out the chip’s “enable” pin, which when driven high, will completely disconnect the common pin (all switches “off”).
