Hello I'm trying to make a new board for medium size nixie tubes like the IN-8 and smiliar ones. Since the PCB cant be very big in size i'm thinking about multiplexing the tubes.
But not the standart-multiplexing with an 7414 IC. I'v used the HV5122/5222 32-bit HV shift registers in my last projects (direct drive) and i like to use just one of these in this project. That would result in two position multiplexing because the IC can handle only 3 tubes at a time. To load the HV5122 it takes 5us. And i would leave the digits on for 15us for example. This would result in 20us cycles at a 50/50 duty rate. Has anybody experience with multiplexing? Is 20us too long, just right, too short? I would like to see no flicker, if possible Thanks for your help. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
