GT9306
The GT9306 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 GT9306 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.
特性
- 2-Bit bidirectional translator for SDA and SCL lines in mixed-mode I2C Applications
- I2C and SMBus compatible - Provides bidirectional voltage translation with no direction pin
- Low 3.5-Ω ON-state resistance between input and output ports provides less signal distortion
- Open-drain I2C I/O ports (SCL1, SDA1, SCL2, and SDA2)
- 5-V Tolerant I2C I/O ports to support mixed-mode signal operation
- High-impedance SCL1, SDA1, SCL2, and SDA2 pins for EN = low
应用
- I2C SMBus, PMBus, MDIO, UART, low-speed SDIO, GPIO, and other two-signal interfaces
- Servers
- Routers (telecom switching equipment)
- Personal Computers • Industrial Automation
