Description

Module with 8-channel multiplexer CD74HC4051 allows you to connect up to 8 signals to a single analog output. The system can work as a demultiplexer and work with digital signals. This means that with a single contact you can display 8 signals or connect 8 sensorsto one terminal. The module is supplied with the voltage from 2 V to 10 V.

 

Specification

  • Supply voltage: 2 V to 10 V
  • 8 channels controlled by 3 input (binary selection)
  • Support bipolar supply (e.g. + / - 5 V)
  • Auxiliary Enable input
  • The set does not contain a goldpin strap, it can be purchased separately and to solder independently.  

Outputs are solder fields for soldering goldpin connectors(2.54 mm raster). Thanks to them, it is possible to connect the system with thebreakout boardor the main module (for example,STM32DiscoveryorArduino) viawires.

Connection

System multiplexer/demultiplexer operates as a switch. Sends a signal from the common output is designated as one of the 8 channel (Y0-Y7). It can also work in the opposite direction, that is, to transmit a signal from one of the 8 channels on the output. The module works for both digital and analog - the voltage value must not exceed the power supply (VCC).

To control the multiplexer you need to connect digital pins S0 - S3 and to specify the correspondingbinary address. Details inthe documentation.

The module also works with digital signals. This means that you can use it to switch the communication interfaces. For example, by connecting oneserial output TX you can communicate with up to 8 receivers RX. Similarly with the I2C bus, SPI and others.
