• Description
• The SparkFun Multiplexer Breakout provides access to all pins and features of the 74HC4051, an 8-channel analog multiplexer/demultiplexer. The 74HC4051 allows you to turn four I/O pins into eight multifunctional, individually selectable signals, which can be used to do everything from driving eight LEDs to monitoring eight potentiometers.
• The 74HC4051 can function as either a multiplexer or a demultiplexer, and it features eight channels of selectable inputs/outputs. The routing of common signal to independent I/O is set by digitally controlling three select lines, which can be set either high or low into one of eight binary combinations.
• One half of the board breaks out the control signals(E, S0-S2)and common input/output(Z). The other side provides access to all eight independent I/O's(Y0-Y7). Both sides include supply and ground connections(VCC, VEE, GND).
