looking at this circuit I am contemplating using a lm3916 in place of the u2067
after drawing out the schematic I got to thinking that perhaps I could eliminate the zener diodes, transistors and pull up resistors.
just connect the 3916 directly to the matrix
see attached drawing and eliminate the described parts.
should work??
velleman circuit **broken link removed**
you can change the r to an s for the matrix. a q for the other half of the matrix driving circuit
any input would be helpful
