It works with both digital and analog signals (the voltage can’t 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 send it the binary address of the channel you want (see the datasheet for details). This allows you to connect up to 16 sensors to your system using only 5 pins!\u003c\/p\u003e\n\u003cp\u003eSince 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’s TX line to 16 device’s RX lines. By using multiple boards, you can create similar arrangements for I2C, SPI, etc.\u003c\/p\u003e\n\u003cp\u003eThe CD74HC4067  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”).\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eNote: The product comes with two variants of ICs i.e CD74HP4067 and CD74HC4067  it doesn't affect the functionality of the product.\u003c\/strong\u003e\u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003chr\u003e\n\u003ch4\u003e\u003cstrong\u003eFeatures :\u003c\/strong\u003e\u003c\/h4\u003e\n\u003col\u003e\n\u003cli\u003e“On” resistance: 70 Ohms @ 4.5V\u003c\/li\u003e\n\u003cli\u003e6ns break-before-make @ 4.5V\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003chr\u003e\n\u003ch5\u003e\u003cstrong\u003eUseful links:\u003c\/strong\u003e\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"http:\/\/cdn.sparkfun.com\/datasheets\/BreakoutBoards\/Analog-Digital-Mux-Breakout-v11.zip\" rel=\"noopener noreferrer\" target=\"_blank\"\u003eEagle Files\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"http:\/\/bildr.org\/2011\/02\/cd74hc4067-arduino\/\" rel=\"noopener noreferrer\" target=\"_blank\"\u003eBildr blog - CD74HC4067\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/github.com\/sparkfun\/Analog_Digital_MUX_Breakout\" rel=\"noopener noreferrer\" target=\"_blank\"\u003eGitHub\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch4\u003e\u003cstrong\u003ePackage Includes :\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003e1 x CD74HC4067 High-Speed CMOS 16-Channel Analog\/Digital Multiplexer Breakout Module - Unsoldered.\u003c\/p\u003e\n\u003cp\u003eSpecification:\u003c\/p\u003e\n\u003ctable class=\"specs-table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eNo. of Channels:\u003c\/td\u003e\n\u003ctd\u003e16\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel No:\u003c\/td\u003e\n\u003ctd\u003eCD74HC4067\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Voltage (VDC):\u003c\/td\u003e\n\u003ctd\u003e2 to 6\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature (°C):\u003c\/td\u003e\n\u003ctd\u003e-55 to 125\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePCB Size ( L x W ) mm\u003c\/td\u003e\n\u003ctd\u003e40 x 18\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight (g):\u003c\/td\u003e\n\u003ctd\u003e3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping Weight\u003c\/td\u003e\n\u003ctd\u003e0.005 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping Dimensions\u003c\/td\u003e\n\u003ctd\u003e9 × 7 × 5 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Jaideep Robotics","offers":[{"title":"Default Title","offer_id":46342280347821,"sku":"43953","price":41.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0773\/7638\/9293\/files\/download_62.avif?v=1782025848","url":"https:\/\/jaideeprobotics.com\/products\/cd74hc4067-high-speed-cmos-16-channel-analog-digital-multiplexer-breakout-module","provider":"Jaideep Robotics ","version":"1.0","type":"link"}
