Driving LEDs
The MG9077 can drive LEDs directly, without the use of an external buffer amplifier. In this case, up to 16 LEDs can be driven directly. This is due to the limitation in IO-pins to 16. Since up to 8 drive and 3 LEDs per slot could be needed, the MG9077 can also use external buffers to drive up to 4 LEDs for each of the 8 slots, which means that 32 LEDs could be driven to represent a particular state.

“It’s like driving a car at night. You never see further than your headlights, but you can make the whole trip that way.”
