TCA9617B - Level-Translating FM+ I2C Bus Repeater

General Description

The TCA9617B is a BiCMOS dual bidirectional buffer intended for I2C bus and SMBus systems.

The device provides bidirectional voltage-level translation (up-translation and down-translation) between low voltages (down to 0.8V) and higher voltages (2.2V to 5.5V) in mixed-mode applications.

Key Features

  • Two-channel bidirectional I2C buffer.
  • Support for standard mode, fast mode (400kHz), and fast mode+ (1MHz) I2C operation.
  • Operating supply voltage range of 0.8V to 5.5V on A-side.
  • Operating supply voltage range of 2.2V to 5.5V on B-side.
  • Voltage-level translation from 0.8V to 5.5V and 2.2V to 5.5V.
  • Footprint and function replacement for TCA9517.
  • Active-high repeater-enable input.
  • Open-drain I2C I/O.
  • 5.5V Tolerant I.
