PCA9306DCUR** is a dual bidirectional I2C-bus and SMBus voltage-level translator from Texas Instruments (TI).

The PCA9306DCUR is a dual bidirectional I2C-bus and SMBus voltage-level translator from Texas Instruments (TI).

Key Specifications:

  • Manufacturer: Texas Instruments (TI)
  • Package: VSSOP-8 (DCU)
  • Operating Voltage Range (Vref1): 1.2V to 3.3V
  • Operating Voltage Range (Vref2): 1.8V to 5.5V
  • Maximum Data Rate: 400 kHz (I2C Fast Mode)
  • Low Standby Current: < 1 µA
  • Bidirectional Voltage Translation: Yes
  • Enable Pin (EN): Allows for power-saving mode
  • ESD Protection: ±2000V HBM (JESD22-A114)

Descriptions:

The PCA9306DCUR is designed for voltage translation between different I2C/SMBus voltage levels without direction control. It features two open-drain channels that allow bidirectional data transfer between devices operating at different voltages.

Features:

  • Bidirectional level shifting without direction control
  • Compatible with I2C and SMBus standards
  • Supports voltage translation between 1.2V and 5.5V
  • Low power consumption
  • Small form factor (VSSOP-8 package)
  • No power supply sequencing required

This device is commonly used in mixed-voltage systems such as battery-powered devices, IoT applications, and embedded systems.
