Truth Table of the 7404 Hex Inverter
How the NOT Gate Works in the 7404 IC
The 7404 hex inverter works using simple NOT gates. A NOT gate is a basic part of digital electronics. It flips the input signal to its opposite. If the input is high (logic 1), the output becomes low (logic 0). If the input is low (logic 0), the output turns high (logic 1). This flipping action is the main job of the 7404 hex inverter.
Each NOT gate in the 7404 IC works on its own. The chip has six NOT gates, making it useful for many tasks. You can use these gates to flip signals, make oscillators, or change logic levels. The simple design of the NOT gate makes the 7404 IC easy to use.
Tip: Each NOT gate in the 7404 IC needs one input and gives one output. This simple setup is great for beginners learning digital electronics.
Input and Output in the 7404 IC Truth Table
The truth table of the 7404 hex inverter shows how its NOT gates work. It explains how an input signal changes to an output signal. Knowing this table helps you use the chip correctly in your circuits.
Here’s the truth table for one NOT gate in the 7404 IC:
| Input (A) | Output (Y) |
|---|---|
| 0 | 1 |
| 1 | 0 |
This table is the same for all six NOT gates in the chip. Each gate follows the same rule, so the chip works consistently. For example, if pin 1A gets a logic 0, pin 1Y will give a logic 1. If pin 2A gets a logic 1, pin 2Y will give a logic 0.
The 7404 IC works with standard TTL logic levels. Inputs are usually between 0V and 5V. A 0V input means logic 0, and a 5V input means logic 1. The outputs match these levels, so the chip works well with other TTL devices.
Note: Use the truth table of the 7404 IC to plan your circuits. It helps you understand how the chip will handle signals.
