About Multiplexer/Demultiplexer ICs

Multiplexer/demultiplexer ICs serve as electronic traffic controllers, enabling multiple signals to share a single transmission path. By selectively routing data streams, these components reduce system complexity and PCB footprint while minimizing crosstalk. Their bidirectional operation provides design flexibility unmatched by discrete solutions.

In modern electronics, mux/demux ICs are indispensable for resource optimization in space-constrained applications. From managing sensor arrays to enabling modular expansion slots, they ensure signal integrity across voltage domains while consuming minimal power. Advanced versions like the 74CBTLV series feature near-zero propagation delay, making them ideal for high-speed data systems.

Packaging Options

Available in industry-standard formats for prototyping and production: Tape & Reel (TR), Cut Tape (CT), and Digi-Reel® packaging. All options include moisture barrier protection and ESD-safe materials.
