It can be seen that to display any single digit number from 0 to 9 in binary or letters from A to F in hexadecimal, we would require seven separate segment connections plus one additional connection for the LED’s “common” connection. Some single displays have also have an additional input pin to display a decimal point in their lower right or left hand corner. In order to produce the required numbers or HEX characters from 0 to 9 and A to F respectively, on the display the correct combination of LED segments need to be illuminated and BCD to 7-segment Display Decoders such as the 74LS47 do just that.Ī standard 7-segment LED display generally has eight (8) input connections, one for each LED segment and one that acts as a common terminal or connection for all the internal display segments. Typically 7-segment displays consist of seven individual coloured LED’s (called the segments), within one single display package. A Digital Decoder IC, is a device which converts one digital format into another and one of the most commonly used devices for doing this is called the Binary Coded Decimal (BCD) to 7-Segment Display Decoder.ħ-segment LED (Light Emitting Diode) or LCD (Liquid Crystal Display) type displays, provide a very convenient way of displaying information or digital data in the form of numbers, letters or even alpha-numerical characters.
