That's from Dieter - almost certainly a "special" - I'd email him and ask if he has any spares. Nick -- You received this message because you are subscribed to the Google Groups "neonixie-l" group. To unsubscribe from this group and stop receiving emails from it, send an email to neonixie-l+u

Bit more on this - European Electronic Counting definitely had custom chips made for them by Emihus Microcomponents Limited, a UK company based in Weybridge, Surrey. Emihus, was an LSI manufacturer specialising in calculator chips, jointly owned by EMI (Electrical and Musical Industries, 49%) a

Doesn't Dieter run Nocrotec instead? Anyway, it's a special but I don't think it can't be replaced with two "non-special" transformers. Of course it will depend on the enclosure. Another alternative is to send it to a motor rewinder... Gastón On Sunday, February 25, 2018 at 4:59:51 AM UTC-3, N

This thread was from a few months ago but wanted to add something. First those chips are pretty cool due to their size so i'll have to try soem at some point. Secondly people keep saying the HV5530 needs 12V logic. I've run these at 3.3V and all seems to be good. I based this on the data she

yes i saw the ROC. my main reason for loosely interpreting the max ratings and going with something within that range was to reduce components (for level shifting and what not). I imagine the better way for me to interpret is to think that the closer I get to the MAX ratings the more likely it

Sorry about that - didn't mean to appear rude - if you read the article there is a picture of the LSI chip - its package is very similar to that used by Mostek in the two example photos, however I suspect that it's a custom design from emihus. Nick -- You received this message because you ar
