• implements logic addition

  • is equivalent to a series switching circuit

  • is an any or all gate

  • is equivalent to a parallel switching circuit


The AND gate is a basic digital logic gate that implements logical conjunction - it behaves according to the truth table to the right. A HIGH output (1) results only if all the inputs to the AND gate are HIGH (1). If none or not all inputs to the AND gate are HIGH, a LOW output results.
