Pinout
1. GND (Pin 7): Ground reference voltage.
2. VCC (Pin 14): Supply voltage, typically 4.5V to 15V.
3. Trigger A (Pin 6): Activates the output low when the voltage drops below 1/3 VCC.
4. Output A (Pin 5): Output of the timer A.
5. Reset A (Pin 4): Resets the timing interval when low.
6. Control Voltage A (Pin 3): Allows external adjustment of the threshold.
7. Threshold A (Pin 2): Ends the timing interval when the voltage exceeds 2/3 VCC.
8. Discharge A (Pin 1): Discharges the timing capacitor when the output is low.
9. Trigger B (Pin 8): Same as Trigger A but for the second timer.
10. Output B (Pin 9): Output of the timer B.
11. Reset B (Pin 10): Same as Reset A but for the second timer.
12. Control Voltage B (Pin 11): Same as Control Voltage A for the second timer.
13. Threshold B (Pin 12): Same as Threshold A but for the second timer.
14. Discharge B (Pin 13): Same as Discharge A but for the second timer.
The NE556DR can operate as a monostable or astable multivibrator, managing two timing circuits independently.
