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
