16 Channel Analog Digital Multiplexer Demultiplexer Module MUX

fungsi nya untuk memperbanyak pin akses analog / digital dgn cara switing Description : - This is a breakout board for the very handy 16- Analog/Digital Multiplexer/Demultiplexer CD74HC4067. - This ip is like a rotary swit - it internally routes the common pin COM in the sematic, SIG on the boardto one of 16 pins ANxx. - It works with both digital and analog signals the voltage can #39;t be higher than VCC, and the connections function in either direction. - To control it, connect 4 digital outputs to the ip #39;s address select pins S0-S3, and send it the binary address of the you want see the datasheet for details. - This allows you to connect up to 16 sensors to your system using only 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 to connect the TX pins of 16 devices to one RX pin on your microcontroller. - You can then select any one of those 16 devices to listen to. - If you want two-way communications, you can add a second board to route your microcontroller #39;s TX line to 16 device #39;s RX lines. - By using multiple boards, you can create similar arrangements for I2C, SPI, etc. - The internal swites are bidirectional, support voltages between ground and VCC, - Have low on resistance and low off leakage, and to prevent crosstalk, perform break-before-make switing. - The board also breaks out the ip #39;s enable pin, whi when driven high, - Will completely disconnect the common pin all swites
