📊 Pin Configuration:

1. GND – Ground reference

2. VCC – Supply voltage (4.5V–15V)

3. Trigger – Activates output when voltage falls below 1/3 VCC

4. Output – Output of the timer

5. Control Voltage – Modifies threshold and trigger voltage

6. Threshold – Ends the timing interval in monostable mode

7. Discharge – Discharges the timing capacitor

8. Reset – Resets the timer when pulled low
