DIP adapters seem to cost around $20 or more.

Oops (red face of shame)... I accidentally linked the .05 pitch
version, you're right.
Here is the .1 version (63cents):

Ahh, I see. Very nice.
How long did it take you to receive your supertex sample units?

Here's a technical drawing of one:

Plug your PLCC in the top of the socket, and insert the socket in the
a 0.1 pitch grid of holes.

To be honest, I have no idea how long they took to arrive.. I sampled those
more than a year ago.
However, most samples seem to arrive in the 1-2 weeks timeframe..
As I mentioned earlier, if the IC you're wanting to use is not available in
PLCC or DIP, you can still pick up one of the nifty
I hear that... Even if I could drum up the spare cash to drop on all
the chemicals, board, equipment, etc. that I would need to start
printing PCBs, I would probably lack the time and the attention span
to get it done (at least without sacrificing something else I'm
already doing). I wish I had a
Adam,
just checked the HV5812 datasheet and it says maximum current is 1mA. Is
that really enough? I mean, most Nixie tubes suck at least 1.5 to 2mA..

Since (the way I understand it) the only way appreciable current will
flow is if the HV5812 pin is pulled low, the important specification
is Isink, which is rated at 3.5mA. Remember that we are using the
HV5812 to pull the cathodes to ground to turn on a number.

Hi,
that makes sense, but I guess you would still run into trouble when
trying to drive ZM1040 at 4.5mA.. I guess the HV9708 is a better choice
in that case.

It looks to me like the HV5812 is really designed to be a HV source driver
(Like for VFD's?), whereas the HV5522 is a sink driver. (Disclaimer: I know
nothing about these chips apart from what I've gleaned of the datasheets in
a handful of minutes.) :D
Sure, Jens. I'll email you directly with the
The HV5522 is available in PLCC package, you can buy DIP sockets for PLCC.
I think that the HV518 is another source driver (designed for driving
VFD's). As I've mentioned before, I know nothing about these chips.. I'm
very excited to hear the results from all of this experimentation.
I'm
Hi again,
thank you all for your ideas. I think I might go for the HV5812 (20
channels) or HV9708 (32 channels) from Supertex, they are both very
neat chips indeed, although quite pricy. (I prefer these chips over
mere driver chips since they have a shift register built in.)
It is not so easy to
Humorously enough, it is the difficulty in purchasing some chips from
mouser/digikey that usually leads me to ordering samples. Mouser has started
stocking _most_ of Maxim-IC's stuff, but before they did, my only source was
to sample them. Same deal with supertex, I couldn't find anywhere to order
I have used the the Supertex HV5812 with IN-16's and IN-14's. It is a
5 volt supply chip that is available in a 28 pin DIP package. It has
20 outputs, so it can drive 2 tubes in direct mode, or 6 tube (2 X 3)
multiplexed. Also, it uses a lot less power than the nixie TTL driver
IC's.
It works
I'd just like to add that Supertex is another company that is very
freehanded with the samples. :) Doesn't cost anything to try out their
parts and see what you think.

Interesting... That's why Atmel is my favorite.

Thanks for the design idea, Michael. I actually have a tube of these in
the drawer that I sampled at one point and have never even looked into
seriously using. The fact that they are SPI is really exciting, since my
preferred uC is the ATTiny2313. Even a direct-drive clock would be
possible on
Just an FYI, Supertex will have an engineer contact you about the
samples. However, since I have a legitimate potential production
usage, I was able to get some.
