Question about PCF8574TS

Hello,

We have switched from the PCA8574ATS to the PCF8574TS because the former component became obsolete.

The original component was advertised to support a maximum frequency of 400 kHz, while the new component is advertised to support a maximum frequency of only 100 kHz.

Currently, we are running the PCF8574TS at a frequency of 250 kHz. Despite exceeding the advertised maximum frequency, the component still operates correctly.

Before we proceed with mass production, we would like to know if you can guarantee that the PCF8574TS will consistently run at 250 kHz.

Thank you.
