7404 2
The 7404 is a type of integrated circuit (IC) known as a hex inverter. It's a 14-pin DIP (Dual In-Line Package) IC that contains six independent inverters.
Here's a brief overview of the 7404 IC:
Pinout:
The 7404 IC has 14 pins, arranged in a dual in-line package (DIP). The pinout is as follows:
- VCC (Positive Supply Voltage)
- GND (Ground)
- Output 1 (Inverter 1)
- Input 1 (Inverter 1)
- Output 2 (Inverter 2)
- Input 2 (Inverter 2) ...
- Output 6 (Inverter 6)
- Input 6 (Inverter 6)
Function:
Each of the six inverters in the 7404 IC has the following function:
- When the input is HIGH (logic 1), the output is LOW (logic 0).
- When the input is LOW (logic 0), the output is HIGH (logic 1).
In other words, the 7404 IC inverts the input signal, producing an output that is the opposite of the input.
Applications:
The 7404 IC is commonly used in digital circuits, such as:
- Logic gates (e.g., AND, OR, NOT)
- Flip-flops and counters
- Oscillators and timers
- Digital filters and amplifiers
Pin 2 (GND) and Pin 1 (VCC):
Pin 2 is connected to ground (GND), while Pin 1 is connected to the positive supply voltage (VCC). These pins provide power to the IC.
Other pins:
The remaining pins (3-14) are the input and output pins for the six inverters. The input pins (4, 6, 8, 10, 12, and 14) receive the input signal, while the output pins (3, 5, 7, 9, 11, and 13) produce the inverted output signal.
