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 (CHANxx). \u003c\/p\u003e\u003cp\u003eIt 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, 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). \u003c\/p\u003e\u003cp\u003eThis 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’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\u003cp\u003eThe 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. \u003c\/p\u003e\u003cp\u003eThe 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\u003cb\u003eSpecification:\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eAnalog signal input: C0-C15, 16-Channel Analog\u003c\/p\u003e\u003cp\u003eAnalog output: DIG\u003c\/p\u003e\u003cp\u003eChannel Control: S0-S3\u003c\/p\u003e\u003cp\u003e2V to 6V operation\u003c\/p\u003e\u003cp\u003e“On” resistance: 70 Ohms @ 4.5V\u003c\/p\u003e\u003cp\u003e6ns break-before-make @ 4.5V\u003c\/p\u003e\u003cp\u003eWide operating temperature range: -55C to 125C\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003ePackage Includes:\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003e1 Piece module\u003c\/p\u003e\u003cp\u003e2 Pieces row of pin\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n","brand":"Aladdin Shoppers: Best Online Shopping site in India - Shop Now!","offers":[{"title":"Default Title","offer_id":42308928176309,"sku":"14012105","price":455.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2570\/5654\/products\/1613059557640f6ojyd.jpg?v=1659092301","url":"https:\/\/aladdinshoppers.com\/products\/16-channel-analog-switch-module-digital-mux-breakout-cd74hc4067","provider":"Aladdin Shoppers","version":"1.0","type":"link"}
