I2c translator/buffer

Hello,

Can PCA9306YZTR be used for level shifting  and also i2c buffer?

Also is there any problem to use ESD protection for I2c lines? will it interfere with I2c operation? 

 

thanks

  • Hello,

    This device is specified as an I2C translator, however, it doesn't exactly act as a buffer as it is based on a switch. When the output is high, the device will have the output pulled up to the higher voltage. This pullup is based on the I2C specification.

    This device has its own ESD protection, but I believe it is common to have ESD on the I2C line.
