so the counterfeit chip seems to have some sort of expected separation from expected vcc and ground pins (indicating resistance and/or logic instead of a dead short) so it should be safe to plug in, and there's an equal resistance between ground and each of the R G B inputs and outputs, meaning they should have the same sort of circuitry between them
looks like the counterfeit ICs might be usable after all... gonna solder it into the master system now
the way china usually counterfeits these ICs is picking any one with the same pin count (in the case of the CXA1145, DIP-28), sometimes desoldered from a working system, filing away the original markings and etching the counterfeit IC number onto it. The chips I have are very obviously fakes, but since the pinouts seem more or less ok (R G and B pins all have the same resistance values, for example, and not a different random pinout) it might be pin-compatible.
