Bus Switches

Bus switches, also called digital switches, are low-resistance CMOS and semiconductor components that function like standard switches and are used to turn ON and OFF electrical connections. These switches are PCB mount devices devoid of moving parts with robust switching performance. They are widely used for hot swapping, voltage translation, hot plug, bus isolation, and help prevent DC power dissipation or noise. 

What are the key specifications and benefits of bus switches?

Bus switches offer a wide variety of benefits with unique features. Some of them include:

  • A large number of pin counts
  • Built with a space-saving design
  • Feature ultra-high-speed digital transmission
  • Offer minimal propagation delay
  • They feature low on-resistance and low capacitance

What are the uses of bus switches?

The primary role of switch bus ICs is the high-speed transmission of digital signals. These digital switches are widely found in electronic applications to prevent current leakage. Some of the most common uses include:

  • Voltage Translation
  • Telecommunications Infrastructure
  • Hot Swapping
  • Cell Phones
  • Capacitance Isolation
  • Notebook PCs
  • Industrial Control
  • PC docking Stations
  • Power Management
  • Uni-directional Level Shifting.
