7 Segment Display (Anode) with MAX7219 / MAX7221 and Raspberry Pi
MAX7219 nad MAX7221 are identical except for two features: The MAX7221 segment drivers are slew-rate limited to reduce EMI; The MAX7221 supports a serial interface that is fully SPI compatible; Conclusion. In this article, I provided all the information you need to get started with the MAX7219 and 7-segment display for your Arduino projects.

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."
Interfacing MAX7219 LED Dot Matrix Display with Arduino
The MAX7219/7221 is an 8-digit, 7-segment common-cathode multiplexed LED display driver which drives up to 40mA segment current while operating from a 4V to 5.5V supply.

This application note discusses the similarities and differences, both hardware and software, between the older MAX7219 and MAX7221 LED display drivers and the newer MAX6950 and MAX6951 drivers. These drivers are five-digit or eight-digit common-cathode LED display drivers controlled through a high-speed serial interface.

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.
