I got ten units of DM9368N from eBay. Test them before use.

DM9368N-HexLED.ino

void displayHex(unsigned int d0){
  (d0 & 0x0001)?digitalWrite(2, HIGH):digitalWrite(2, LOW);
  (d0 & 0x0002)?digitalWrite(3, HIGH):digitalWrite(3, LOW);
  (d0 & 0x0004)?digitalWrite(4, HIGH):digitalWrite(4, LOW);
  (d0 & 0x0008)?digitalWrite(5, HIGH):digitalWrite(5, LOW);
  digitalWrite(6, LOW);
  digitalWrite(6, HIGH); // data latched
}

unsigned int data=0;

void setup() {
  // put your setup code here, to run once:
  int i;

  for(i=2; i<8; i++){
    pinMode(i, OUTPUT);
    digitalWrite(i, LOW); // DATA=0, Latch pass through, RBI enabled
  }
  digitalWrite(6, HIGH); // data latched

  Serial.begin(115200);
  Serial.write("**DM9368N Hex 7-seg Driver Test");

}

void loop() {

  char text[32];

  // put your main code here, to run repeatedly:

// lights on for 500ms  
  displayHex(data++);
  sprintf(text, "display %x\n", data & 0x000f);
  Serial.print(text);

  digitalWrite(7, HIGH); // RBI disabled = ligths on
  delay(500);

// lights off 
  displayHex(0);
  digitalWrite(7, LOW); // RBI enabled = ligths off
  delay(500);

}
