We have high temp electronics that are used in deep wells, nuclear reactors and scientific instruments… Do they go to 400C+? I don’t know but even on digikey you can find IC’s with operating temperatures above 200C and even 250C fairly easily. The issue with Venus is really cost vs benefit any probe would have a very short life span as in hours to maybe maybe days. At the same cost you can send probably multiple missions to Mars that would last months if not years. We had probes on Venus using 1960’s technology we can do that again. Selling the political oversight and even the public on this however is far harder than designing and building them.
