SPARKFUN MULTIPLEXER BREAKOUT – 8 CHANNEL (74HC4051)

SparkFun Multiplexer Breakout – 8 Channel (74HC4051)

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

Features:

Switches ****og or digital signals
8 channels controlled by 3 select inputs
Wide voltage supply range: 2 – 10V
Bipolar supply support (e.g., ±5V)
Optional enable input
Breadboard compatible breakout

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).
