MAX7219 Serially Interfaced, 8-Digit LED Display Drivers - DIP-24
The MAX7219 are compact, serial input/out-put common-cathode display drivers that interface microprocessors (?Ps) to 7-segment numeric LED displays of up to 8 digits, bar-graph displays, or 64 individual LEDs. Included on-chip are a BCD code-B decoder, multiplex scan circuitry, segment and digit drivers, and an 8x8 static RAM that stores each digit. Only one external resistor is required to set the segment current for all LEDs.
