H = HIGH Voltage Level L = LOW Voltage Level X = Immaterial Functional Description The DM9368 is a 7-segment decoder driver designed to drive 7-segment common cathode LED displays. The DM9368 drives any common cathode LED display rated at a nominal 20 mA at 1.7V per segment without need for current limiting resistors. This device accepts a 4-bit binary code and produces output drive to the appropriate segments of the 7-segment displa...
