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.

What is the difference between the MAX7219 and the MAX7221? The MAX7221 is a higher-performance version of the MAX7219, with additional features such as a serially-controlled shutdown mode and an on-chip BCD-to-7-segment decoder. However, it is generally more expensive than the MAX7219. For most of the nobby projects, my first preference is.

Yes, high impedanceis basically open circuit. "When the MAX7219 is in shutdown mode, the scan oscillator is halted, all segment current sources are pulled to ground, and all digit drivers are pulled to V+, thereby blanking the display. The MAX7221 is identical, except the drivers are high-impedance."
