Drivers

Abstract: This application note provides details on how to connect the MAX6958 and MAX6959 LED display
drivers to 5-digit LED displays for counter display applications requiring the display range -39999 to 39999
without decimal points.


The MAX6958 and MAX6959 are 4-digit, 9-segment LED drivers which use a reduced pin count multiplexing
