Hi folks,
well, I have had it with the Russian driver ics... Have only about 20
left, and for my next project I would be needing quite a lot of these.
And what I really dislike about these is that you can only select one
output at a time. So I was thinking it might be time to move on ;-)
I read on Mikes website (http://www.electricstuff.co.uk/
nixie_sources.html) that the Supertex chips are quite nice, and I know
that many others use these chips in their clocks, as well.
But I am quite confused. Which chip is the one for me? I can not
solder SMD, so I need the 44 pin PLCC versions that can easily be used
with a socket in 2.54mm format.
But other than that, there are sooo many HV driver ics. Is there a
chip that you can recommend? (I'd like to drive primitive IN-14 at
180V or so).
Best regards,
Jens
I find that the TI SN75468 or the Toshiba TD62084 Darlington driver
arrays work just fine. They cost about 1/4 the price of a Supertex chip,
and come in DIP form so they're easy to use.
They need a Zener diode and resistor to hold the commutator diode pin at
~50V.
