TAS5766M: I2C interface

Part Number: TAS5766M
Other Parts Discussed in Thread: TCA9517A, , TCA9406

Hi,

A customer wants to connect TAS5766M with 5 volts I2C-bus he used to use. But TAS5766M is not able to connect with 5 volts I2C-bus directly, because SCL and SDA are not 5 volts tolerant terminals. Therefore he thought to put Level-Shifting I2C Bus Repeater such as TCA9517A between TAS5766M and 5 volts I2C bus. But VOL of TAS5766M does not satisfy VILC of TCA9517A. Is there any good solution?

Best regards,

Akio Ito

    Hi Akio,

    We used the TCA9406 in one of our audio EVMs. You can take a look at this device.

    BTW, I'm not an expert on the i2c level shifters. You may want to post another e2e question about the i2c level shifters in other forums so that other experts can provide more options.
