Altium. Reusing schematic symbols for pin-compatible parts.

+3
−0

I want to create a schematic symbol and reuse it for multiple ICs which have identical pinouts. For example, OpaMPS, or the venerable SN74LS00, SN74HC00, SN74HCT00. How can I do this in an Altium library without copying and pasting the symbol every time?

I'd like to create a library where I don't need to remember all the pin-compatible sets, and I can go by the part number in the library. I want to find out what kind of support Altium has for that.

I know I could drop a symbol and change the comment from ADuM2250 to ISO1640DWR. But that would not be the workaround I'm looking for.

For a comparison, OrCAD has aliases for schematic symbols. Each symbol can have multiple model numbers associated with it.

Something like Eagle's device attributes?
Olin Lathrop‭ wrote 2 months ago:

In Eagle you can make generic symbols that can be customized with "attributes", which are sortof like environment variables that are set in the device. The device is what binds a symbol to one or more packages, and is a container for higher level information above the packages and symbols. Maybe Altium has a similar mechanism?

Altium has got closer to Eagle with its current library architecture. This is a recent development. Altium started with a different library architecture [which was less sophisticated, in my opinion], and it still supports its historical architecture.
