7400 IC quad 2-input NAND gate IC 14-pin DIP
The IC 7400 provides four independent 2-input NAND gates inside a single 14-pin Dual In-line Package (DIP). It belongs to the standard 7400 TTL (Transistor-Transistor Logic) family and operates on a 5V power supply. Each gate performs a basic NAND logic operation, which outputs LOW only when both inputs are HIGH. Engineers use this IC to build larger digital systems from simple logic functions. The 7400 delivers fast switching performance and maintains excellent noise margins.
Its TTL-compatible inputs and outputs ensure smooth integration with other TTL components. Designers choose the 7400 IC for its consistent behavior, quick response, and reliable performance in both prototype and production-level circuits. Electronics students often use it to learn about logic gates, while professionals rely on it in control circuits, digital signal systems, and logic-based automation. This IC offers a compact, low-cost solution for creating versatile digital logic designs. From basic logic circuits to sophisticated control units, the IC 7400 continues to serve as a cornerstone in digital electronics.
