MAX7219 SMD  8-Digit LED Display Drivers
Item # 20319
Serially Interfaced, 8-Digit LED Display Drivers.
Description: The MAX7219/MAX7221 are compact, serial input/output common-cathode display drivers that interface microprocessors (μPs) 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. The MAX7221 is compatible with SPI™, QSPI™, and MICROWIRE™, and has slewrate-limited segment drivers to reduce EMI.

FEATURES
♦ 10MHz Serial Interface
♦ Individual LED Segment Control
♦ Decode/No-Decode Digit Selection
