7400 Quad 2-Input NAND Gate IC

The 7400 is a classic TTL logic IC containing four independent 2-input NAND gates in a single 14-pin DIP package. It is one of the most widely used chips in digital electronics. Because a NAND gate is a universal gate, the 7400 can be wired to build any other logic function, including AND, OR, NOT, NOR and XOR, as well as flip-flops, latches and oscillators. That makes it a staple for students, hobbyists and engineers. Key Features Four independent 2-input NAND 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 Reliable, low-cost and easy to use for both learning and prototyping Specifications Type: Quad 2-Input NAND 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 = NOT (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)
