About this product
A 7404 hex inverter IC, a TTL logic chip containing six independent NOT gates. Each gate outputs the opposite logic level of its input. This is an unbranded copy of the standard 7404, used in digital logic projects, signal inversion and simple logic circuits.

Frequently asked questions
How should I power and wire the unused inputs?
Connect VCC to 5V and GND to ground. Do not leave unused inputs floating; tie them to a defined logic level, either ground or VCC, so the outputs stay stable.
What is it used for?
Each NOT gate inverts its input, so a HIGH input gives a LOW output and the reverse. It is used to invert signals, drive active-low logic and build simple RC oscillators.
