Pinout
Here is the pin configuration and function:
- Pin 1, 2: Inputs for the first NOR gate.
- Pin 3: Output for the first NOR gate.
- Pin 4, 5: Inputs for the second NOR gate.
- Pin 6: Output for the second NOR gate.
- Pin 7: Ground (GND).
- Pin 8: Output for the third NOR gate.
- Pin 9, 10: Inputs for the third NOR gate.
- Pin 11: Output for the fourth NOR gate.
- Pin 12, 13: Inputs for the fourth NOR gate.
- Pin 14: Positive supply voltage (VCC).
Each NOR gate within the IC performs the logical NOR operation, which outputs a high level (1) only when both inputs are low (0). NOR gates are fundamental building blocks in digital electronics and are used in various applications for implementing logic functions.
