Pin assignements in a quad comparator are overwritten

[jjmcuppen]

I use an LM339 quad comparator, wich is equivalent to LM2901, and used the spice model supplied by texas instruments ti.com.
It turns out one has to redo the pin assignments of the model since that looks like a 5pin single comparator model only.
However when subsequently assigning pins for units A, B, C and D which are of course different, then the assignements for the last unit so edited, overwrite the pin assignements for the other units. That probably makes connections (everything connected to IN- in any of the units gets connected) within the circuit that are not correct or intended.
Is this analysis correct and can it be solved?
Thanks,
Jan

LM339 assigning Symbol Pin to Model Pin

If you have a multi-unit symbol (e.g. from a dual opamp, a dual bipolar transistor or a quad nand gate …) and your ngspice model from the vendor is addressing only a single device, for example the comparator model has only 5 pins (in+, in-, out, vcc, vee), but your symbol has 14, then you have to create an intermediate ngspice subcircuit. I have explained this in my tutorial at KiCad Eeschema as GUI for ngspice, tutorial for setting up the simulation or in a video at https://www.youtube.com/wat…

that answers this question.
