I'm working on a design with some Nixie tubes (a clock, specifically to start, but I'm gonna have a ton left over for other things), and due to the rather expensive nature of the K155ID1/74141 ICs, I'm not real eager to just plug things in the way I think they should go and see if it blows anything up.
My understanding is that the ICs should take +5V and GND from my controller (Arduino, for instance) or directly from my power rail, as well as taking the BCD in the DCBA pins from my controller. To strike the Nixie tubes, I need 170+V at a relatively low amperage. From what I've read about the BCD decoder, my "outputs" (pins 1, 2, 8, 9, 10, 11, 13, 14, 15, 16) can be attached to the cathode pin on the Nixie tube corresponding to the number I want to light up.
I assume then that the ground pin on the BCD decoder needs to share a common ground with both the power source for the Nixie tubes and the power source for the IC itself. My question is, will that voltage (even with the low amperage) blow up my K155ID1's?
