I'm beginner in electronics.
I want to make footprint of HV5622 shift register using Eagle cad. But I don't know how to set the pad spacing and pad size of the footprint.
-
There are three values in the datasheet: min, nom, max. I don't know which one to use.

And, in the datasheet, the leg length of the chip is 1.95mm, but I don't know how to set the length of the pad.
Best Answer
Use nominal values (+ 0.2mm) to make your pad. The pitch is 1.27mm. You have enough space to increase the width.
In this case, I'd say you should increase the length of your pad (by 0.8 to 1mm, I guess) since that wouldn't interfere with the pitch of your device.
PS: Once you have designed the land pattern, review and measure all the dimensions just to be sure. :)
