CD4052BE Dual 4-Channel Analog Multiplexer/Demultiplexer | ATMOSFÆR ENGINEERING

CMOS logic IC featuring two independent 4-channel analog multiplexers/demultiplexers with digital control. Allows routing of analog or digital signals between one common I/O and four independent channels per switch. Bidirectional operation enables both multiplexing (many-to-one) and demultiplexing (one-to-many) configurations. Ideal for expanding limited microcontroller analog inputs, signal routing, and audio/sensor switching applications.
