Analog multiplexers, also known as MUXs or data selectors, select one of many input signals and connect it to a single output or transmission line. Multiplexers reduce the number of required transmission lines by allowing multiple signals to share a single line at different times. Alternatively, demultiplexers take a signal from a single input and switch it to multiple outputs at different times.
Overview
Our comprehensive portfolio of 3.3V and 5V analog multiplexer and demultiplexer ICs deliver high-speed switching performance. Designed to prevent propagation delay and ground bounce noise, these ICs are an excellent fit for bidirectional interfaces in mixed-supply buses and applications that require isolation and protection. With robust design and versatility, these switches enable efficient signal routing in a wide variety of systems.

Selecting Multiplexers & Demultiplexers
Key parameters of multiplexers and demultiplexers include:
- On-resistance: The path resistance when switched on. Renesas' multiplexers/demultiplexers provide an on-resistance of 5ohms.
- Transition time: The amount of time it takes for the multiplexer/demultiplexer to transition from one input to the next. Renesas’ products transition in 6ns.
- Bandwidth (-3dB point): The range of acceptable switching frequencies. Renesas’ multiplexers/demultiplexers provide up to 830MHz bandwidth and are ideal for high-performance video signal switching, audio signal switching, and telecom routing applications.
- Crosstalk: The amount of noise transmitted from one switch/signal to another when in operation. Renesas’ multiplexers/demultiplexers offer excellent crosstalk performance up to -115dB at 50kHz, -100dB at 5MHz, and -66dB at 30MHz.
- Off-isolation: The isolation of the switches within the device when the switches are off. Renesas’ multiplexers/demultiplexers offer superb off-isolation up to -90dB at 50kHz, -60dB at 5MHz, and -50dB at 30MHz.
