Description
The Sparkfun Multiplexer Breakout is a device that allows access to all pins and features of the 74HC4051, an 8-channel analog multiplexer/demultiplexer. It can turn four I/O pins into eight individually selectable signals, which can be used for various purposes such as driving LEDs or monitoring potentiometers. The 74HC4051 can function as either a multiplexer or a demultiplexer and has eight channels of selectable inputs/outputs. The routing of common signals to independent I/O is controlled by three select lines, which can be set to one of eight binary combinations. The board has two sides, one for control signals and common input/output and the other for all eight independent I/Os. Both sides have supply and ground connections.
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/OS (Y0-Y7). Both Sides Include Supply And Ground Connections (Vcc, Vee, Gnd).
