it's too complicated, I have bought like this, it's much easier than your supplier, and it's much cheaper, I can help you to purchase these if you want.
Hi Sean,

Could you share information where to buy those things? I look for it to develop a printer using FPGA based hardware.

Hi, sorry I didn't login in for a long time, just get your message right now, i have send you my email by PM.

@dragonator.... I have tried to build HP45 driver circuit using Arduino Mega and TLC59213 it was working too. When i was shifted to HEF4017 4018 for addressing i am facing some issues. I am not getting the output as i have got with 5 TLC ics.
But my planning is to build the driver chip using xilinx fpga and 2n7002 mosfets. Can anybody guide me to do it. Thanks

Hello and welcome Priyashree

Do you have any schematics or images of your circuit. The 4017 circuit has not really ever failed me, so I am curious how you are doing it.
