Quad AND (2 input) 7408

The Quad AND (2 input) 7408 is a 74-series logic IC that contains four independent 2-input AND gates in one 14-pin package. Each gate gives a HIGH output only when both of its inputs are HIGH. It is a standard chip for digital electronics courses and logic experiments, and for combining enable signals in real circuits.
