An eight-channel analogue multiplexer that connects any one of eight pins to a single common pin, chosen with three address lines plus an inhibit input. Because the switches are bidirectional it works as a demultiplexer too, and it passes real analogue voltages - not just logic levels - with about 125 ohms of on-resistance. The classic use is reading eight sensors or potentiometers through one Arduino analogue input, at the cost of three digital pins.
Key features
- Switches 1 of 8 channels to a common pin
- Bidirectional - works as mux or demux
- Passes analogue signals, not just logic
- About 125 ohms on-resistance
- Three address pins plus an inhibit input
- Supply 3V to 20V, 16-pin DIP
