The SparkFun Multiplexer Breakout provides access to all pins and
features of the 74HC4051, an 8-channel analog

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

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).
