The 74ls47n chip, described in detail within the 74ls47n Datasheet, is commonly used to drive seven-segment displays. These displays are composed of seven individual LEDs arranged in a specific pattern that can be selectively lit to form numerals from 0 to 9. The 74ls47n takes a BCD input (a binary representation of a decimal digit) and translates it into the appropriate signals to illuminate the correct segments on the display. The 74ls47n Datasheet provides the truth table, showing exactly which segments will be turned on for each BCD input value. The chip utilizes active-low outputs. The table below gives a few input/output cases
| BCD Input (DCBA) | Seven Segment Output (a b c d e f g) |
|---|---|
| 0000 (0) | 0 0 0 0 0 0 1 |
| 0001 (1) | 1 0 0 1 1 1 1 |
