74ls04 DIP IC


SKU: 000366 Categories: , Tags: , , , ,


The 74LS04 is a widely used integrated circuit (IC) that belongs to the 74LSxx series of logic gates. It is specifically a hex inverter, which means it contains six individual logic gates, each of which performs the NOT operation on a single input signal. Here are the key features and details of the 74LS04 IC:

1. **Function:** The 74LS04 is a hex inverter IC, which means it has six independent inverters, each taking a single digital input and producing the logical complement (NOT) of that input at the output.

2. **Logic Symbol:** The logic symbol for a hex inverter looks like this: ![74LS04 Logic Symbol](https://upload.wikimedia.org/wikipedia/commons/4/48/74LS04_Symbol.png)

3. **Pin Configuration:** The 74LS04 has 14 pins, with two pins for each of the six inverters. The pins are labeled as follows: A1, Y1, A2, Y2, A3, Y3, A4, Y4, A5, Y5, A6, and Y6. “A” pins represent the inputs, and “Y” pins represent the outputs.

4. **Voltage Compatibility:** The 74LS04 is designed to work with 5-volt TTL (Transistor-Transistor Logic) logic levels. It is not directly compatible with modern 3.3V or 2.5V logic systems without level shifting.

5. **Propagation Delay:** The 74LS04 has a specific propagation delay, which is the time it takes for the output to change after the input has changed. This delay is typically in the range of a few nanoseconds.

6. **Low Power:** It is considered a low-power IC, making it suitable for various battery-operated or power-sensitive applications.

7. **Applications:** The 74LS04 is commonly used for signal inversion, level shifting, and basic digital logic functions in various electronic circuits and projects. It’s also used in combination with other logic gates to implement complex logical operations.

8. **DIP Package:** The 74LS04 is typically available in a Dual In-Line Package (DIP), which is a through-hole package with two rows of pins that can be easily inserted into a breadboard or soldered onto a PCB.

9. **Heat Dissipation:** The 74LS04 can generate some heat during operation, so proper ventilation or heat-sinking may be required in high-frequency or high-power applications.

The 74LS04 is a fundamental component in digital electronics and is widely used in logic design and prototyping. Its basic function of inverting a digital input signal to its complement makes it a versatile building block for various digital circuits and systems.
