I know there were several plasma driver chips used in the early 90s (I have some SN751518s used from a laptop neon display) I have data on these and they are open drain - ideal nixie drivers but these chips have been obsolete for years.
Modern-ish plasma televisions use newer chips. I recently scrapped a plasma tv and it uses SN755870 (I also have a board containing SN755881 from a different TV) These seem to be absolutely made as nixie drivers. They run off 5v (unlike the supertex devices), have push-pull outputs, any output could be 200v or ground. This could be a universal driver for direct-drive (64 output pins) or multiplexed (pins can be set to HT and used as anode drivers) Does anyone have any data on SN755870 and sn755881 ? I can find a pinout and that's it. These chips seen cheap and readily available new or from old TVs Cheers, Andrew -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
