This circuit only uses la7770 chip. Which would not require a big fan out. Maybe not the LA7770 itself, but the involved resistive voltage dividing network consisting of R1, R3 and the unshown pull-up at LA7770. What exactly does the micro? It seems to me, that he wants to strobe/enable the signal transmission somehow. Makes this sense? Kai |
