The PCA9670PW,112 can support I2C bus frequencies up to 400 kHz.
Yes, the PCA9670PW,112 can be used as a level shifter for 5V to 3.3V or 1.8V, but it's not recommended as it's not its primary function and may not provide the best performance.
To configure the PCA9670PW,112 for bidirectional voltage translation, connect the VCC pin to the higher voltage supply, and the VCCx pins to the lower voltage supply. Then, use the OE (Output Enable) pin to control the direction of the voltage translation.
The PCA9670PW,112 can sink or source up to 8mA of current per channel.
Yes, the PCA9670PW,112 can be used in a hot-swappable application, but it's essential to ensure that the power supplies are properly sequenced to avoid damage to the device.
