... The MM74C911 allows individual control of any segment in the 4-digit display. The number of segments per digit can be expanded without any external components. For exam- ple, two MM74C911’s can be cascaded to drive a 16-seg- ment alpha-numeric display. The display controllers receive data information through 8 data lines a, b… ...

... Since every seg- ment is under microprocessor control, great versatility is obtained. Low power standby operation occurs with both SOE and DIO inputs HIGH. This condition forces the MM74C911 to a quiescent state typically drawing less than supply current with a standby supply voltage as low as 3V. 2 ...
