74LS47 BCD to 7-Segment Decoder/Driver IC – 16-Pin, Open Collector | Jaycar

You've got a BCD counter feeding a display and need something that actually drives the segments without you wiring up a tangle of transistors. The 74LS47 takes your 4-bit BCD input and lights the right segments on a common-anode 7-segment display. Open-collector outputs mean you set the current limit with a single pull-up resistor. One chip, one clean connection to your display. Sorted

• Decodes 4-bit BCD input to drive a 7-segment display
• Open-collector outputs for flexible current limiting
• 16-pin package for straightforward PCB or breadboard mounting
• 74LS-series logic family for reliable digital switching
• Jaycar-brand component available through local Australian supply
