First of all I apologize if this is in the wrong section as this is my first post.
My next project is for a microcontroller class that's centered around the 8051. Having recently dug up a large cache of Nixie tubes I naturally have to build a clock.
I did a little digging and came up with the HV5522 Serial to parallal converter with open drain outputs. This is exactly what I need but it's surface mount, and for the moment I'm limited to parts I can put on strip board. Anyway, I'm looking for a part with at least 10 open drain outputs that I can drive with TTL.
I know I could do this with a shift register driving a bunch of FETs, but with a 6 digit clock and 10 control lines per digit I'm trying to cut down on individual parts. A few of my friends have made attempts at their own clocks, and I choked when I saw their 30+ transistors on each tube control module.
Regards,
Ben
