Features & Applications

The PCA9306 is a dual bidirectional I2C-bus and SMBus voltage-level translator with an enable (EN) input, and is operational from 1.0 V to 3.6 V (Vref(1)) and 1.8 V to 5.5 V (Vbias(ref)(2)).

The PCA9306 allows bidirectional voltage translations between 1.0 V and 5 V 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.

Features and benefits:

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
Provides bidirectional voltage translation with no direction pin
Low 3.5 O ON-state connection between input and output ports provides less signal distortion
Open-drain I2C-bus I/O ports (SCL1, SDA1, SCL2 and SDA2)
5 V 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 pinout for ease of printed-circuit board trace routing
