TCA9617A - Bus Repeater

General Description

The TCA9617A is a BiCMOS dual bidirectional buffer intended for I2C bus and SMBus systems.

It can provide bidirectional voltage-level translation (uptranslation and down-translation) between low voltages (down to 0.8 V) and higher voltages (2.2 V to 5.5 V) in mixed-mode applications.

Key Features

  • 1 Two-Channel Bidirectional I2C Buffer.
  • Support for Standard Mode, Fast Mode (400 kHz), and Fast Mode+ (1 Mhz) I2C Operation.
  • Operating Supply Voltage Range of 0.8 V to 5.5 V on A-Side.
  • Operating Supply Voltage Range of 2.2 V to 5.5 V on B-Side.
  • Voltage-Level Translation From 0.8 V to 5.5 V and 2.2 V to 5.5 V.
  • Footprint and Function Replacement for TCA9517.
  • Active-High Repeater-Enable Input.
  • Open-Drain I2C I/O.
  • 5.5-.
