CJMCU-9306 device is a dual bidirectional I2C and SMBus voltage-level translator with an enable (EN) input
and is operational from 1.2-V to 3.3-V VREF1 and 1.8-V to 5.5-V VREF2.
The PCA9306 device allows bidirectional voltage translations between 1.2 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.
In addition to voltage translation, the PCA9306 device can be used to isolate a 400-kHz bus from a 100-kHz busy controlling the EN pin,
and disconnecting the slower bus during fast-mode communication.
Specification for PCA9306 Bidirectional I2C Bus and SMBUS Voltage Level Converter:
- 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 1.5 ns 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 3.5 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
- Flow through pinout for ease of printed-circuit board trace routing
- ESD protection exceeds 2000 V HBM per JESD22-A114 and 1000 V CDM per JESD22-C101
