BCD to Seven Segment Display
Advanced Technocracy Inc. is Manufacturer, Exporter & Supplier of BCD to Seven Segment Display
BCD to Seven Segment Display (using Light Emitting Diodes). The decoder driver circuit is used to drive its binary coded decimal output from switches. The BCD to seven segment decoder driver IC 7446/47A which consists of 45 diodes, 16 resistors and 7 transistors. There are 4 switches corresponding to 4 variables A,B,C and D. The switches are so connected that the two terminals of the switch corresponds to a logic ‘1’ and logic ‘0’ respectively in one position of the switch. When the switch position is changed, the two terminals just inter-change their A,B,C and D both in the true form, as well as in the false form. Thus depending upon the state of the switches and their relative position a particular digit is displayed on the display panel.
The board consists of the following built-in parts :
