Hailege 2pcs CD74HC4067 CMOS 16 Channel Digital Analog Multiplexer Breakout Module
Hailege 2pcs CD74HC4067 CMOS 16 Channel Digital Analog Multiplexer Breakout Module
Description: This is a breakout board for the very handy 16 channel analog/digital multiplexer/demultiplexer CD74HC4067. This chip is like a rotary switch - it internally directs the common pin (COM in the wiring diagram, SIG on the board) to one of 16 channel pins (CHANxx). It works with both digital and analog signals (the voltage must not be higher than VCC), and the connectors work in both directions. To control it, connect 4 digital outputs to the address selection pins of the chip (S0-S3) and send it the binary address of the desired channel (see the data sheet for details). So you can connect up to 16 sensors to your system with just 5 pins. Since the Mux/Demux also works with digital signals, you can use it to route serial data at the TTL level to or from multiple devices. For example, you can use it to connect the TX pins of 16 devices to an RX pin on your microcontroller. You can then select one of these 16 devices you want to listen to. If you want bi- directional communication, you can add a second board to route your microcontroller's TX line to the RX lines of 16 devices. By using multiple boards, you can create similar arrangements for I2C, SPI etc. Features: 1. 2 V to 6 V operation. 2. "On" resistance: 70 ohms @ 4.5V 3. 6 ns break-before-make @ 4.5 V 4. Wide operating temperature range: -55" to 125? Package includes: 2 x CD74HC4067 CMOS 16 channel digital analogue multiplexer breakout
