X-rayed an isolated RS-485 transciever (
TI ISOW1412) with @artelse . The chip appears to have 5 separate dies + a (ceramic?) transformer mounted onto the metal leadframe. That's a lot going on in such a small package.

@cibomahto@social.v.st @artelse@mastodon.social That block diagram looks a lot more like the actual part than I'm used to. Wonder why the receiver and tristate buffer are different dies

@cibomahto@social.v.st @artelse@mastodon.social that's much more integrated than the typical ethernet magnetics

@artelse@mastodon.social @cibomahto@social.v.st and suddenly you can understand the high cost of such devices.
