MAX6955AAX+ Frequently Asked Questions (FAQs)

• What is the maximum current that the MAX6955AAX+ can sink or source?
  The MAX6955AAX+ can sink up to 25mA per output and source up to 10mA per output.
• How do I configure the MAX6955AAX+ for 7-segment display mode?
  To configure the MAX6955AAX+ for 7-segment display mode, set the MODE pin high and the DISP pin low. Then, use the data inputs (D0-D3) to select the desired segment patterns.
• What is the purpose of the DISP pin on the MAX6955AAX+?
  The DISP pin is used to enable or disable the display. When DISP is high, the display is enabled, and when DISP is low, the display is disabled.
• Can I use the MAX6955AAX+ to drive an LCD display?
  No, the MAX6955AAX+ is designed to drive LED displays, not LCD displays. It provides a high-voltage output (up to 25V) that is not suitable for LCD displays.
• How do I interface the MAX6955AAX+ with a microcontroller?
  The MAX6955AAX+ can be interfaced with a microcontroller using a 4-bit parallel interface. The microcontroller can write data to the MAX6955AAX+ using the data inputs (D0-D3) and the clock input (CLK).
