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

    Check if the 4514 (4-bit latch 4-16 line DECODER) in the 45xx.lbr is

    compatible.
