Function: Use the ADC to collect 16 analog signals.
Use CD74HC4067's 16 -channel analog signal switch
Analog signal input: C0-C15 16 channels
Simulation output: DIG
Channel control: S0-S3
Description:This is a breakout for the very handhandy 16 -Chinesenel Analog/Digital Multiplexer/DEMULTIPLEXELEXELEXEL4067. This chip is like a Rotary Switch - OUTES The Common Pin (COM in the Schematic, SIG on the Board) to One of 16 ChannelPins (channels). It world with both digital and anygnaLs (the voltage cannot be higher than vcc), and the connections function in either direction. To control IT, Connect 4 Digital Outputs to the Chip's Address Select Pins (S0-S3), and see it the binary address of the channel you want (See the datasheet for details). This all all bouct up to 16 Sensors to your System users 5 pins!
SINCE The MUX/DEMUX Also Works with Digital Signals, you can use it to pipe TTL-Level Serial Data to or From Multiple Devices. For Example, You Could USE IT T T T Tation o Connect The TX Pins of 16 Devices to One RX Pin on Your MicroControllerYou can then select any one of the Those 16 Devices to Listen to. If you want two-way commit, you can add a second board to route your micro organ's tx. Line to 16 device's rx lines. by using multiple boards, you can create similarArrangements for i2C, SPI, ETC.
The Internet Switches are bidirectional, support voltages between group and vcc, have low "on" resision and low "off" Leakage, and to prevent crasstalk, P. Erform "Break-BEFORE-MAKE" switching."Pin, Which When Driven High, Will Completely Disconnect The Common Pin (ALL SWITCHES" OFF ").
