onsemi PCA9306
The PCA9306 is a dual bidirectional I2C−bus and SMBus voltage−level translator with an enable (EN) input. The PCA9306 allows bidirectional voltage translations between 1.0 V and 5 V without the use of a direction pin. The PCA9306 is not a bus buffer that provides both level translation and physical capacitance isolation to either side of the bus when both sides are connected.| Part No. | PCA9306 |
