Working Principles

The SN74CBT3126DG4 is a digital multiplexer/demultiplexer that routes digital signals between multiple inputs and outputs. It operates based on the control inputs (A1-A4, B1-B4) and the output enable input (OE#). When OE# is low, the device functions as a multiplexer, selecting one of the four input lines (A1-A4) and transmitting it to the corresponding output line (Y1-Y4). When OE# is high, the device functions as a demultiplexer, transmitting the selected input line to one of the four output lines based on the control inputs (B1-B4).

Detailed Application Field Plans

The SN74CBT3126DG4 finds applications in various digital systems where signal routing and data selection are required. Some specific application fields include:

1. Data communication systems: Used for channel selection and data routing in multiplexed communication channels.
2. Digital audio/video systems: Enables switching between different audio/video sources and destinations.
