ON Resistance: 70Ω @ 4.5VCC; 60Ω @ 6VCC 2V to 6V operation Operating temperature: -55°C to +125°C
This is a breakout board for the TI CD74HC4067 16-Channel Analog/Digital Multiplexer/Demultiplexer. This chip can be used to connect 16 analog sources (like sensors) to five pins on a microcontroller. Four of the pins must be digital pins; one pin must be an analog-to-digital conversion pin. This is a great way to connect a lot of sensors to a few pins.
You also can run the mux/demux the other direction. One serial stream connected to the SIG pin can be piped to multiple outputs.
The mux/demux also works with digital signals (like serial, I2C, SPI). This means you can hook up multiple serial devices (like a GPS TX pin and an XBee DOUT pin) to one RX pin on a microcontroller.
The IC can control analog voltages that vary across the voltage supply range. The bidirectional switches allow any analog or digital input to be used as an output and vice-versa with a "Break-Before-Make" switching of 6ns at 4.5V. In addition, the switches have low "on" resistances and low "off" leakages. It includes an enable control which, when High, will set all switches to the "off" state.
