Hi Team，

Could you tell me why the pin numbers and functions defined by the chip are different from those of the recommended layout？

I guess the layout example was simply copied from the SN74HCS244. But whether a pin is input or output does not really make a difference for the layout.

Hi Depeng,

Thanks for bringing this to our attention. This is a mistake, I'll have this issue fixed in our next datasheet update. As Clemens stated the layout would remain the same just make sure to terminate unused inputs to GND or Vcc.

Regards,

Sebastian
