Pinout
The 74HCT02D has a total of 14 pins. The pin configuration is as follows:
1. Pin 1, 2: Input A1, B1 (for the first NOR gate)
2. Pin 3: Output Y1 (first NOR gate)
3. Pin 4, 5: Input A2, B2 (for the second NOR gate)
4. Pin 6: Output Y2 (second NOR gate)
5. Pin 7: Ground (GND)
6. Pin 8: Output Y3 (third NOR gate)
7. Pin 9, 10: Input A3, B3 (for the third NOR gate)
8. Pin 11: Output Y4 (fourth NOR gate)
9. Pin 12, 13: Input A4, B4 (for the fourth NOR gate)
10. Pin 14: Positive supply voltage (Vcc)
Each NOR gate in the IC performs the logical NOR operation, where the output is true (low) only when both inputs are false (low).
