New user frustrated - can't find part  :(

Former Member

Hi,

 

I just purchased Eagle CAD to draw a schematic for a project that was dumped in my lap.  Not only am I brand new to eagle but I'm also not experienced with electronics; I know enough to get basic stuff done, but oftens not enough to fully understand why it works (or doesn't)! image

 

So I've isntalled Eagle, watched tutorials, read the manual (I really did) and googled for various answers.  I STILL cannot figure out where to find a part to represent a 74HCT4514.  I've found parts that seem similar (e.g. 45xx > 4514 > 4514D) but the pin labels don't match what I'm expected (specifically, where is /E and /LE?)  The part in eagle has /ST and /INH however I'm unfamiliar with these labels.

 

Of the 6 hours I've spent ACTUALLY drawing a schematic I would say that 90% of that time has been spent search for parts.  I checked the eagle site for downloadable libraries but didn't see anything that seemed better than what is already installed.

 

Can someone please let me know if there is a pin compatible part in eagle for a 74HC4514?  If I DO have the correct part already, what do /ST and /INH stand for?

 

Thanks for reading,

Steve

    Create the part for yourself. It's not hard, and it's the only way to be

    sure that the part is correct for your use. This is a pretty trivial

    device, and almost any Eagle tutorial will walk you through the process.

     

    Depending on some random library part is generally a bad idea. Even for

    something as trivial as a SMD resistor there are different suggested pad

    dimensions depending on whether the board will be assembled via wave

    soldering vs reflow.
