TL494: DTC variation data of TL494

Part Number: TL494

Dear, All

It is a question about DEAD-TIME CTRL of TL494.
It is about the regulation of Input threshold voltage (DEAD-TIME CTRL) of Datasheet P6.
The customer uses the created evaluation board to measure "Zero duty cycle".
The default value of "Zero duty cycle" written in the data sheet lists only TYP value and MAX value.
However, the value measured by them was greatly deviated to the side smaller than the TYP value.
Therefore, they are worried about how much MIN value should be assumed.
Could you please tell us the reference values such as measurement data in multiple lots?

Thanks, Masami M.
