TCA9543A - Low Voltage 2-Channel I2C Bus Switch

Description

The TCA9543A is a dual bidirectional translating switch controlled by the I2C bus.

The SCL/SDA upstream pair fans out to two downstream pairs, or channels.

Either individual SCn/SDn channel or both channels can be selected, determined by the contents of the programmable control register.

Features

  • 1 1-of-2 Bidirectional Translating Switches.
  • I2C Bus and SMBus Compatible.
  • Two active-low interrupt inputs.
  • Active-low interrupt output.
  • Active-low reset input.
  • Two address pins allowing up to four TCA9543A devices on the I2C bus.
  • Channel selection via I2C bus, in any combination.
  • Power-up with all switch channels deselected.
  • Low RON switches.
  • Allows voltage-level translation between 1.8-V, 2.5-V, 3.3-V, an.
