IC 7427 – Triple 3-Input NOR Gate

The IC 7427 is a TTL logic IC that contains three independent 3-input NOR gates in a single 14-pin DIP package. Each gate performs the standard NOR logic function—outputting LOW when any of the inputs is HIGH—making it ideal for digital logic control and signal processing circuits.

This IC is widely used in combinational logic designs, timing control circuits, and educational experiments where multi-input NOR functionality is required.
