The OR gate is a digital logic gate that implements logical disjunction – it behaves according to the truth table below. A HIGH output (1) results if one or both the inputs to the gate are HIGH (1). If neither input is high, a LOW output (0) results. In another sense, the function of OR effectively finds the maximum between two binary digits.
INPUT | OUTPUT | |
---|---|---|
A | B | A OR B (Q) |
0 | 0 | 0 |
0 | 1 | 1 |
1 | 0 | 1 |
1 | 1 | 1 |
