PCF8574: spike time

Part Number: PCF8574

Tool/software:

Hi All,


I have a question about the PCF8574 datasheet.

The Spike filter limit time has been changed in the Revision History.

Can you tell me why it was changed from 100nsec to 70nsec?

I think the change was made to the PCF8574 in order to prevent it from affecting communications in noisy environments.


Best Regards,
Ishiwata
