Create numeric readouts with the 74LS47 BCD-to-7-Segment Decoder/Driver IC. This 16-pin chip converts 4-bit binary-coded decimal (BCD) signals into segment-control outputs for a common-anode 7-segment LED display. Its active-low, open-collector outputs work alongside lamp-test, display-blanking, and zero-suppression functions for flexible display control. Operating from a 5V supply (4.75–5.25V), it is a practical choice for digital counters, clock displays, and educational electronics projects. External current-limiting resistors are required for LED segments.
