ADUM1251 - Dual I2C Isolators

Download the ADUM1251 datasheet PDF. This datasheet also covers the ADUM1250 variant, as both devices belong to the same dual i2c isolators family and are provided as variant models within a single manufacturer datasheet.

Description

The ADuM1250/ADuM12511 are hot swappable digital isolators with nonlatching, bidirectional communication channels that are compatible with I2C interfaces.

This eliminates the need for splitting I2C signals into separate transmit and receive signals for use with standalone optocouplers.

Features

  • Bidirectional I2C communication.
  • Open-drain interfaces.
  • Suitable for hot swap.
