The 74ls21 is a dual 4-input AND gate, meaning it contains two independent AND gates within a single package. The AND gate is a fundamental building block in digital logic, producing a HIGH output only when all of its inputs are HIGH. If any input is LOW, the output will also be LOW. A simple truth table demonstrates this:
| Input A | Input B | Input C | Input D | Output |
|---|---|---|---|---|
| 0 | X | X | X | 0 |
| X | 0 | X | X | 0 |
| X | X | 0 | X | 0 |
| X | X | X | 0 | 0 |
| 1 | 1 | 1 | 1 | 1 |
The 74ls21 finds applications in a wide range of digital circuits, including address decoding, data selection, and control logic.
