Hi team,

I want to check why the UCD9090A spec for the Tr and Tf is more strict than normal I2C(1000ns)? Do youhave some ideas here? Thanks,

Hello

You do not have the latest data sheet. Both devices have the same rising and falling time which is up to 300ns.

Hi Yihe,

so it's only suitable for the I2C FAST mode, right? Thanks.

Hello

We support both 100Khz and 400Khz. The values in the table are for 400Khz only.

Thanks
