7408 Quad 2-Input AND Gate IC

The 7408 is a TTL logic IC containing four independent 2-input AND gates in a single 14-pin DIP package. Each gate outputs HIGH only when both of its inputs are HIGH. It is one of the most commonly used basic logic chips, used wherever two signals must both be present before an action is triggered. The 7408 is a good fit for students, hobbyists and engineers building digital circuits, control logic and lab projects. Key Features Four independent 2-input AND gates in one package Standard TTL logic family, compatible with 5V digital circuits 14-pin DIP package, breadboard and PCB friendly Fast switching, with a typical propagation delay of about 10 ns Low cost and easy to use for learning and prototyping Specifications Type: Quad 2-Input AND Gate Logic Family: TTL (7400 series) Supply Voltage (VCC): 4.75V to 5.25V (5V nominal) Package: DIP-14 Operating Temperature: 0°C to 70°C (commercial grade) Logic Function: Y = A AND B Pin Configuration Pin 14: VCC Pin 7: GND Gate 1: pins 1, 2 (inputs), pin 3 (output) Gate 2: pins 4, 5 (inputs), pin 6 (output) Gate 3: pins 9, 10 (inputs), pin 8 (output) Gate 4: pins 12, 13 (inputs), pin 11 (output)
