MAX7219CNG 8 Digit LED Display Driver IC
₵16.00
The MAX7219/MAX7221 are compact, serial input/out-put common-cathode display drivers that interface microprocessors (μPs) to 7-segment numeric LED dis-plays 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 8×8 static RAM that stores each digit. Only one external resistor is required to set the segment current for all LEDs
