Interface FPGA with Print Head

[saeednowroozi]

Hi All
I must design a interface with fpga ( spartan6-144 pin ) with a head print(xaar128) but voltage fpga is 3.3 and head is 5 volt. what is the best solution and low cast for this problem?I see for connection between fpga and head used lvc541a but i cant access this ic, I can use adg3304? I must design pcb in 2 layer!
other question, How can i design this lines? Why designer putting up holes in the lines?

There are buffers which may be suitable for your solution. Look for buffer with dual voltage (one side of the buffer would be powered by 3.3 and the other by 5V)
