Luke,

> Please tell me connect 74HC574 Q1-Q8 pin's parts is what ?

sorry, I don't understand the question,
the 'Q' number insdie the device refers to the latch number inside the
device..
the 'Q' number on output refers to the 'bit' value where Q15 is the biggest
and Q0 is the smallest.

The 74hc574s are being used as a 16Bit DAC, its a cheap and fairly quick way
to do it.
