BCD to Seven Segment Display
Product Code : JA-DET-1527
The BCD to seven segment display board demonstrates how a 7446/47A decoder driver turns a 4-bit BCD input into a decimal digit on a common-anode LED display. Four SPDT switches give the logic 1 and 0 inputs for variables A, B, C and D, and a 5 V, 100 mA regulated supply is built in (SKU JA-DET-1527).
