Citing a Datasheet or Technical document in IEEE style
I cite datasheets as manuals. For example, I recently cited the LTC3600. My experience is with biblatex and JabRef. In JabRef I can choose the 'manual' type and can fill in the organisation, datasheet title, url, and use a (part) number. I believe that most citation managers have a field for 'number', you can use this for part codes.

The resultant biblatex code can look like this:

@Manual{ltc3600,
  title        = {{15V}, {1.5A} Synchronous Rail-to-Rail Single Resistor Step-Down Regulator},
  year         = {2011},
  number       = {LTC3600},
  note         = {Rev. D},
  organization = {Linear Technology},
  url          = {https://www.analog.com/media/en/technical-documentation/data-sheets/3600fd.pd},
}


And the output in IEEE style like this:



I believe this is similar to the Tex SE answer you linked.
