TCA9517 - Level-Shifting I2C Bus Repeater

General Description

The TCA9517 is a bidirectional buffer with level shifting capabilities for I2C and SMBus systems.

It provides bidirectional voltage-level translation (uptranslation/down-translation) between low voltages (down to 0.9 V) and higher voltages (2.7 V to 5.5 V) in mixed-mode applications.

Key Features

  • 1 Two-Channel Bidirectional Buffer.
  • I2C Bus and SMBus Compatible.
  • Operating Supply Voltage Range of 0.9 V to 5.5 V on A-side.
  • Operating Supply Voltage Range of 2.7 V to 5.5 V on B-side.
  • Voltage-Level Translation From 0.9 V - 5.5 V to 2.7 V - 5.5 V.
  • Footprint and Functional Replacement for PCA9515B.
  • Active-High Repeater-Enable Input.
  • Open-Drain I2C I/O.
  • 5.5-V Tolerant I2C and Enable Input Support Mixed-Mode Signal Op.
