Pinout
1. Ground (Pin 1): Connects to the circuit's ground.
2. Trigger (Pin 2): Initiates the timing interval when voltage falls below 1/3 of VCC.
3. Output (Pin 3): Outputs the timer's signal, either high or low.
4. Reset (Pin 4): Resets the timer; active low.
5. Control Voltage (Pin 5): Allows changing the threshold voltage, typically not used and connected to a capacitor for stability.
6. Threshold (Pin 6): Ends the timing interval when the voltage exceeds 2/3 of VCC.
7. Discharge (Pin 7): Discharges the timing capacitor through this pin when the output is low.
8. VCC (Pin 8): Connects to the positive supply voltage.
The LM555CMX is typically used in monostable (single pulse generation) or astable (continuous pulse generation) modes.
