PCA9306D,118

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

• 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 and multiple leaders
• Provides bidirectional voltage translation with no direction pin
• Low 3.5Ω 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 pinout for ease of printed-circuit board trace routing
