Introduction

AI Translation

The PCA9306 device is a dual-channel bidirectional I2C and SMBus voltage level translator with an enable (EN) input. It can operate within the range of 1.2V to 3.3V REF1 and 1.8V to 5.5V REF2. The PCA9306 device can achieve bidirectional voltage conversion between 1.2V and 5V without the need for a direction pin. This switch has a low on-state resistance (RON), enabling connections to be established with the shortest propagation delay. When EN is high, the translator switch turns on, and the SCL1 and SDA1 I/Os are connected to the SCL2 and SDA2 I/Os respectively, enabling bidirectional data flow between ports. When EN is low, the translator switch turns off, and there is a high-impedance state between the ports. In addition to voltage conversion, the PCA9306 device can also be used to isolate a 400kHz bus from a 100kHz bus by controlling the EN pin to disconnect the slower bus during fast-mode communication.

Features

AI Translation
  • 2-bit bidirectional translator for SDA and SCL lines in I2C applications
  • Compatible with I2C and SMBus
  • Maximum propagation delay less than 1.5ns, supports standard-mode and fast-mode I2C devices and multiple masters
  • Voltage level translation between: 1.2V VREF1 and 1.8V, 2.5V, 3.3V, or 5V VREF2; 1.8V VREF1 and 2.5V, 3.3V, or 5V VREF2; 2.5V VREF1 and 3.3V or 5V VREF2; 3.3V VREF1 and 5V VREF2
  • Bidirectional voltage translation without direction pin
  • 3.5Ω low on-state resistance between input and output ports reduces signal distortion
  • Open-drain I2C I/O ports (SCL1, SDA1, SCL2, and SDA2)
  • 5V-tolerant I2C and I/O ports support mixed-mode signal operation
  • High-impedance SCL1, SDA1, SCL2, and SDA2 pins when EN is low
  • Latch-up-free operation enables isolation when EN is low
  • Straight-through pin arrangement simplifies PCB routing
  • ESD protection exceeds JESD 22: 2000V Human Body Model (A114-A), 1000V Charged Device Model (C101)
