PCA9306
Description
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.
Key Features
- 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 NXP Semiconductors PCA9306 Dual bidirectional I2C-bus and SMBus voltage-level translator
- Less than 1.5 ns maximum propagation delay to accommodate Standard-mode and Fast-mode I2C-bus devices and multiple controllers
- Allows voltage level translation between: - 1.0 V Vref(1) and 1.8 V, 2.5 V, 3.3 V or 5 V Vbias(ref)(2) - 1.2 V Vref(1) and 1.8 V, 2.5 V, 3.3 V or 5 V Vbias(ref)(2) - 1.8 V Vref(1) and 3.3 V or 5 V Vbias(ref)(2) - 2.5 V Vref(1) and 5 V Vbias(ref)(2) - 3.3 V Vref(1) and 5 V Vbias(ref)(2)
- 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-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
