LTC4310-1 - Hot-Swappable I2C Isolators

Description

The LTC®4310 provides bidirectional I2C communications between two I2C buses whose grounds are isolated from one another.

Each LTC4310 encodes I2C bus logic states into signals that are transmitted across an isolation barrier to another LTC4310.

Features

  • n Bidirectional I2C Communication Between Two Isolated Buses n Full Isolation with Inexpensive Ethernet Transformers or Capacitors n Low Voltage Level Shifting n I2C Maximum Operating Frequency: 100kHz for LTC4310-1 400kHz for LTC4310-2 n I2C Specification Compliant VOL, VIL n ±5kV Human Body Model ESD Protection n Rise Time Accelerators n SDA, SCL Hot-Swapping n Very Low Shutdown Current n Stuck Bus Disconnect and Recovery n Thermal Shutdown n 10-Lead MSOP and 3mm × 3mm DFN Packages Appli.
