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.

Famous quotes containing the word driving:
“As it grew darker, I was startled by the honking of geese flying low over the woods, like weary travellers getting in late from Southern lakes, and indulging at last in unrestrained complaint and mutual consolation. Standing at my door, I could hear the rush of their wings; when, driving toward my house, they suddenly spied my light, and with hushed clamor wheeled and settled in the pond. So I came in, and shut the door, and passed my first spring night in the woods.”
—Henry David Thoreau (1817–1862)
