Hey gang--
I am looking for an Eagle symbol for a 3-digit, 7-segment led display (the all-in-one units, not 3 individual 7-segments displays)

I am planning on use this with a a MAX7219/7221 chip, for reference during reading.
First.. I have to ask about the differences between these two displays I found:
1 has 12 pins:

1 has 11 pins: (which might make more sense?..to me I guess? SegA-G + DP = 8, 3 digits = 3GNDS = 11 pins total?)

I searched and searched.. and finally found a 3-digit, 7-segment display Eagle part/symbol..
but it has 12 pins..
SEGA-G + DP
C1
C2
C3 (which I'm assuming are the common grounds/cathodes?)
and then an "L" pin?
(possibly a LATCH pin perhaps?)
either way.. I dont believe is the one/type of display I want to use in the schematic as it doesnt match any of the actual/physical displays I have found/will be using?
Anybody have one? a link to a lib with one? Used one in a project before?
Also some insight on these differences?
again.. my current approach is to make a simple 'backpack' PCB (BOB) for this 3-digit display... with the MAX and vRegulator circuit(s) on the back....etc.. (this is to be used as a counter)
the MAX needs 3 lines to the Arduino.. and multiplexes so I don't need to worry about high power requirements
thanks again!
