ISO1640 - Hot-Swappable Bidirectional I2C Isolators

Description

The ISO1640, ISO1641, ISO1642, ISO1643 and ISO1644 (ISO164x) devices are hot swappable, lowpower, bidirectional isolators that are compatible with I2C interfaces.

The ISO164x supports UL 1577 isolation ratings of 5000 VRMS in the 16-DW package, and 3000 VRMS in the 8-D package.

Features

  • Robust Isolated Bidirectional, I2C Compatible, Communication.
  • ISO1640: Bidirectional SDA and SCL communication.
  • ISO1641: Bidirectional SDA and unidirectional SCL communication.
  • ISO1642/3/4: Bidirectional SDA and SCL communication with either 2 or 3 unidirectional GPIO channels.
  • Hot-Swappable SDA and SCL.
  • Bidirectional data transfer up to 1.7 MHz Operation.
  • Up to 3 additional unidirectional isolated GPIO channels supporting 50 Mbps s.
