We made some hundreds copies of article on TOP234Y without any problems during 5 years. But now we buy a party of TOP234Y (about 100 chips) which does not work in this article. The marking on chips of this pary is follow:
H311
TOP234Y
E22557J (and E22557L)
Is this party have any peculiarity?
The cips of of any other party which we have work in this article correctly.
