Sir,
I am using FYS-15011BS-11 7-segment common anode display and DM7447N IC to drive it. But Whenever I give inputs to its A B C D inputs according to the truth table I am getting reverse output, it means when I apply A B C D INPUTS as 0 0 0 0 respectively 7 segment should display '0' means a b c d e f segments should get on and g segment should get off. But I am getting exactly opposite behaviour. a b c d e f segments are getting off and g segment is getting on. What could be the reason ? Can you please guide me. It is grateful if you can provide the datasheet of mentioned BCD to 7 segment decoder IC 9603B DM7447N.
