Texas Instruments PCA9306
The PCA9306 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.| Part No. | PCA9306 |
