What is BU1922?


This is RDS / RBDS decoder.

A demultiplexer, also known as a "demux," is a digital circuit that takes a single input signal and directs it to one of several possible outputs. It is essentially the reverse of a multiplexer, which takes multiple inputs and directs them to a single output.

[ Detailed Data ]


The basic design of a demultiplexer involves using a set of logic gates to decode the control signals and direct the input signal to the selected output channel. The input signal is usually passed through a series of AND gates, with each gate corresponding to one of the possible output channels. The control signals are used to enable the appropriate AND gate, while the other gates are disabled.
