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.

主要特性

  • 双通道双向I²C总线中继器 
  • 端口A和端口B可实现1.08 V至3.6 V的电压电平转换
  • 保证1 MHz操作(真正的I²C FM+)并支持FM和SM操作
  • 无静态电压偏移
  •  施密特触发器输入通过滤除信号的噪声成分来提高抗噪能力
  • 所有I/O均具备输入和输出上升沿信号加速器
  • 无锁操作
  • 无毛刺且与序列无关的IC上电
  • I²C时钟拉伸支持
  • 开漏输入/输出
  • 兼容I²C总线和SMBus协议
