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."

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.
