The IC 7425 is a TTL logic IC that contains two independent 4-input NOR gates in a single 14-pin DIP package. Each gate performs the NOR logic operation, outputting a LOW signal when any of its four inputs is HIGH—making it a vital component in logic design and control systems.
Designed using TTL (Transistor-Transistor Logic) technology, the 7425 offers fast switching speeds and is commonly used in high-speed digital circuits and industrial logic controllers.
