Iv seen 4 of these chips been driven by PIC's before and they can only drive 20ma per pin,
Does this mean to drive this CLK IO i need (18ma * 40) = 720ma so nearly 1amp to drive some IO? or have i done my math wrong?
Is it for pins OSC and SYNC? If
can you get buffers/line drivers that can supply 720ma??,
i sort of wanted just ONE Clk wire comin from my control line that would go to all the HT1632C boards
