Pinout
1. Ground (Pin 1): Connects to the ground of the circuit.
2. Trigger (Pin 2): Responsible for starting the timing interval in monostable mode. A negative pulse on this pin causes the timer to begin its cycle.
3. Output (Pin 3): Delivers the timer's signal, which can be high or low depending on the mode of operation.
4. Reset (Pin 4): A low signal on this pin resets the timer, overriding any other input. When not used, it should be connected to VCC to avoid accidental resets.
5. Control Voltage (Pin 5): Allows the modification of the threshold and trigger levels. Often connected to ground via a capacitor if not in use.
6. Threshold (Pin 6): Monitors the voltage to end the timing interval in monostable mode.
7. Discharge (Pin 7): Used to discharge a capacitor between intervals in astable mode or control the timing in monostable mode.
8. VCC (Pin 8): Connects to the positive supply voltage.
This IC is versatile and used in various timing, delay, and pulse generation applications.
