Working Principles

The SN74CBT3126RGYR is a digital multiplexer/demultiplexer IC that routes digital signals between multiple input/output channels. It operates based on the principle of CMOS transmission gates, which allow or block the flow of signals depending on the control inputs.

When the enable (EN) input for a specific channel is high, the corresponding input signal is connected to the output pin. Conversely, when the enable input is low, the connection is broken, isolating the input from the output.

Detailed Application Field Plans

The SN74CBT3126RGYR finds applications in various digital systems where signal routing and selection are required. Some potential application fields include:

Data communication systems
Telecommunication equipment
Test and measurement instruments
Audio/video switches
Industrial automation systems
