Logic and signal switches are the electronic components that are used to control the flow of current in a system. These components are used to direct the flow of electrical signals within a system. The MC14066BDG is a 4-channel CMOS analog multiplexer/demultiplexer manufactured by Texas Instruments. It is a monolithic integrated circuit, meaning it is constructed solely from one piece of silicon. The MC14066BDG provides four channels of logic-switchable analog signals. It also functions as a multiplexer or demultiplexer, providing multiple channels and less noise when compared to single-channel logic switches.

The MC14066BDG is comprised of a linear array of eight N-channel MOSFETs (metal oxide semiconductor field effect transistors). These MOSFETs are arranged into four channels, each of which may accept an analog signal, and two switches for each channel. The four channels are designated I, II, III, and IV. The switches for each channel are labeled A and B. Signals applied to I, II, III and IV are routed to A, B, C and D, respectively, when the channel-select switches are actuated. The MC14066BDG also provides dual logic control inputs (“A” and “B”) to enable the four digital outputs.

The MC14066BDG is well suited for applications requiring routing or multiplexing of logic signals. It can be used to switch and multiplex audio signals, providing noise reduction when compared to single-channel logic switches. Additionally, this IC is ideal for systems which require the routing of multiple signals. Examples of common applications include simultaneous switching of multiple audio signals, alternate switching of multiple power sources, and multiplexing of analog signals.

The MC14066BDG is an analog multiplexer/demultiplexer that provides superior flexibility, noise reduction, and control when compared to conventional logic switches. This IC features two independent digital control inputs (“A” and “B”) enabling the selection of four digital channels. The on-resistance (Ron) of the switches is very low and the four channels are divided into two pairs. The MC14066BDG also provides dual logic control inputs (“A” and “B”) allowing the four digital outputs to be separately enabled or disabled.

In summary, the MC14066BDG is a CMOS analog multiplexer/demultiplexer. It can route up to four analog signals between two pairs of channels, and has dual logic control inputs allowing the four digital outputs to be separately enabled or disabled. The typical on-resistance (Ron) of the device is very low and provides noise reduction when compared to single-channel logic switches. The MC14066BDG is an ideal solution for applications requiring routing or multiplexing of digital logic signals.
