1-line to 8-line demultiplexer consist of eight AND gates, all of them connected to a single line data input.
2
It takes single input and distributes it over several outputs.
3
It is used as anti-clock demultiplexers in synchronous data transmission systems in the receivers and security monitoring systems etc.
4
