Part Number: LSF0108-Q1

Hi team,

A-side High level voltage is higher than Vref_A.

The datasheet figure also appears to be higher than 1.8V.

Could you provide me the reason?

If this cannot be avoided, what is the voltage range?

Best regards,

Hi Tomoaki,

The signal you are referencing is an input to the device so its possible it is slightly higher than 1.8 V. How much higher is the voltage? Are you pulling it up to a different supply?

I recommend watching the training videos below that cover the LSF family operation:
