Der analog digital CMOS Multiplexer IC ist in folgenden Ausführunegn verfügbar:

•  2 Stück CD4051 single 8 Kanal demultiplexer multiplexer DIP-16 IC

Multiplexer basieren auf einer Selektionsschaltung in der analogen und digitalen Elektronik, mit der aus einer Anzahl von Eingangssignalen eines ausgewählt und an den Ausgang durchgeschaltet werden kann. Die 405X Multiplexer sind biderektional einsetzbar und können sowohl im

•  DEMUX Betrieb um z.B. Sensor Signale zu empfangen
• MUX Betrieb um z.B. Signale zu Schalten (Schaltfunktion)

Die 405X Serie basiert auf verschiedenen Multiplexern um unterschiedliche Anzahl von

• Kanälen
• Ein- / Ausgängen (Pins)
• Transmission Gate

zu unterstützen.

Multiplexer are perfect to expand the amount of analog or digital Outputs and Inputs for example MCU’s

The analog digital CMOS Multiplexer IC is available

•  2 pcs. CD4051 single 8 channel demultiplexer multiplexer DIP-16 IC

Multiplexer is a device that selects one of several analog/digital signals and forwards the selected input into a single line. The 405X Multiplexer can be use in both directions

• DEMUX for example to receive signal from sensors
• MUX for example to send signal (power supply usually) to sensor

The CD405X series is based on different types of multiplexers, to operate with different numbers

• of channels
• input / output (pins)
• Transmission Gate

CD405X Multiplexer Demultiplexer IC Features:

The CD4051B device is a single 8-channel multiplexer having three binary control inputs, A, B, and C, and an inhibit input. The three binary signals select 1 of 8 channels to be turned on, and connect one of the 8 inputs to the output.
