Overview

This dual bidirectional I2C and SMBus voltage-level translator, with an enable (EN) input, is operational from 1.2-V to 3.3-V VREF1 and 1.8-V to 5.5-V VREF2. The PCA9306-Q1 allows bidirectional voltage translations between 1.2 V and 5 V, without the use of a direction pin.

  • AEC-Q100 qualified for automotive applications - Temperature grade 2: -40°C to 105°C, TA - HBM ESD classification level H2 - CDM ESD classification level C4B
  • 2-Bit bidirectional translator for SDA and SCL lines in mixed-mode I2C applications
  • Compatible with I2C and SMBus
  • Less than 1.5-ns maximum propagation delay to accommodate standard-mode and fast-mode I2C devices and multiple controllers
  • Allows voltage-level translation between - 1.2-V VREF1 and 1.8-V, 2.5-V, 3.3-V, or 5-V VREF2 - 1.8-V VREF1 and 2.5-V, 3.3-V, or 5-V VREF2 - 2.5-V VREF1 and 3.3-V, or 5-V VREF2 - 3.3-V VREF1 and 5-V VREF2
  • Provides bidirectional voltage translation with no direction pin
  • Low 3.5-Ω ON-state connection between input and output ports provides less signal distortion
  • Open-drain I2C I/O Ports (SCL1, SDA1, SCL2, and SDA2)
  • 5-V tolerant I2C I/O ports to support mixed-mode signal operation
  • High-impedance SCL1, SDA1, SCL2, and SDA2 pins for EN = low
