Bus Switches

A Bus Switch, also known as a Digital Switch is a semiconductor device that turns on and off an electrical connection. Bus Switches are PCB mount devices that act in the same way as a normal mechanical switch. Unlike a mechanical switch, a Bus Switch has no moving parts, ensuring greater performance. RS Components offer a range of high-quality electronic components from leading brands including Texas Instruments, Nexperia, Maxim Integrated, Analog Devices and ON Semiconductor.

What is a Bus Switch?

A Bus Switch is an array of high-speed, very low-resistance CMOS switches which are used to transmit a group of signals called a signal bus.

What are Bus Switches used for?

The compact ICs are used for high-speed digital signal transmission. Bus switches or digital switches are used in a vast array of electronic applications. Some of the most common are

  • Voltage translation
  • Hot Swapping
  • Capacitance isolation
  • PC docking stations
  • Power management

Advantages and Key Features

  • Space-saving design
  • Ultra-high-speed
  • Low on-resistance
  • Low capacitance
  • Minimal propagation delay
