Pinout
1. Pin 1 (Ground): Common ground for both timers.
2. Pin 2 (Trigger 1): Trigger input for Timer 1. A low voltage triggers the timer.
3. Pin 3 (Output 1): Output of Timer 1.
4. Pin 4 (Reset 1): Resets Timer 1 when set low.
5. Pin 5 (Control Voltage 1): Allows control of the threshold voltage for Timer 1.
6. Pin 6 (Threshold 1): Input to the comparator for Timer 1.
7. Pin 7 (Discharge 1): Discharge pin for the timing capacitor of Timer 1.
8. Pin 8 (Vcc): Positive supply voltage for both timers.
9. Pin 9 (Discharge 2): Discharge pin for the timing capacitor of Timer 2.
10. Pin 10 (Threshold 2): Input to the comparator for Timer 2.
11. Pin 11 (Control Voltage 2): Allows control of the threshold voltage for Timer 2.
12. Pin 12 (Reset 2): Resets Timer 2 when set low.
13. Pin 13 (Output 2): Output of Timer 2.
14. Pin 14 (Trigger 2): Trigger input for Timer 2.
Each timer can operate in either monostable or astable mode, suitable for generating precise time delays or oscillation.
