I²C switches and multiplexers

Efficiently manage multiple I²C devices with scalable performance

Our I²C switches and multiplexers portfolio enables seamless communication between a single I²C controller and multiple target devices, even with shared addresses, by selectively routing signals. These devices simplify complex system architecture, resolve address conflicts, and support scalability. Ideal for designs requiring signal integrity, fault isolation, or flexible expansion, they provide reliable, efficient, and cost-effective solutions for managing I²C communication across diverse platforms.

Key features and benefits

  • Facilitates voltage-level translation between I²C devices, streamlining integration 
  • Resolves I²C address conflicts via individual device selection
  • Isolates faulty devices (incl. bus hangup devices) to prevent system failures and maintain integrity
  • Extends I²C addressability for managing multiple peripherals
  • Availalbe in TSSOP24 and HWQFN24 for space constrained applications
