SN74AHC123A: About the leading edge detector

Part Number: SN74AHC123A

Hi team,

I'm trying to use the SN74AHC123ADR as a leading edge detector as the guide instructs, just like the following figure

However, I can only get the output pulse which has a min width of 53ns, while I look up the datasheet it says the min width is ns

Could you please tell me how to do this?

Best Regards,

Ziyu
