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.<\/p>\n\n
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.<\/p>\n\n
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\u2019s (Y0-Y7). Both sides include supply and ground connections (VCC, VEE, GND).<\/p>\n\n
