74LS47 7-Segment Driver IC 74LS47 7-Segment Driver IC
24 In stock
The SN74LS47 is a 7-segment Driver IC. It is used to drive a 7-segment display without the need of a microcontroller. It accepts decimal values (Binary coded) as inputs and provides a pattern on output pins that can display from 0 to 9 on a 7-segment display. The 74LS47 accepts four lines of BCD input data, generates their complements internally, and decodes the data with seven AND/OR gates having open-collector outputs to drive indicator segments directly.
It can operate from 3V to 18V and can source up to 25mA on each output pin, which is high enough to illuminate the LEDs in a 7-segment display directly.
