Product Overview

The PCA9306D is a dual bidirectional I²C-bus and SMBus voltage-level Translator IC with an enable (EN) input and operational from 1.0 to 3.6V (Vref(1)) and 1.8 to 5.5V (Vbias(ref)(2)). It allows bidirectional voltage translations between 1.0 and 5V without the use of a direction pin. The low ON-state resistance (Ron) of the switch allows connections to be made with minimal propagation delay. When EN is HIGH, the translator switch is on and the SCL1 and SDA1 I/O are connected to the SCL2 and SDA2 I/O, respectively, allowing bidirectional data flow between ports. When EN is LOW, the translator switch is off and a high-impedance state exists between ports. The PCA9306D is not a bus buffer like the PCA9509 or PCA9517A that provide both level translation and physically isolates the capacitance to either side of the bus when both sides are connected. The IC only isolates both sides when the device is disabled and provides voltage level translation when active.
  • 2-bit Bidirectional Translator for SDA and SCL Lines in Mixed-mode I²C-bus Applications
  • Standard-mode, Fast-mode and Fast-mode Plus I²C-bus and SMBus Compatible
  • Less than 1.5ns maximum propagation delay to accommodate standard-mode and fast-mode I²C-bus devices
  • Provides Bidirectional Voltage Translation with No Direction Pin
  • Low 3.5R ON-state Connection Between Input and Output Ports Provides Less Signal Distortion
  • Open-drain I²C-bus I/O Ports (SCL1, SDA1, SCL2 and SDA2)
  • 5V Tolerant I²C-bus I/O Ports to Support Mixed-mode Signal Operation
  • High-impedance SCL1, SDA1, SCL2 and SDA2 Pins for EN = LOW
  • Lock-up Free Operation
  • Flow Through Pin-out for Ease of Printed-circuit Board Trace Routing
  • ESD Protection Exceeds 2000V HBM per JESD22-A114 and 1000V CDM per JESD22-C101
