Pinout
1. Ground (GND): This pin is connected to the ground or negative supply voltage.
2. Trigger: A negative pulse on this pin (below 1/3 VCC) sets the output high if the flip-flop is reset.
3. Output: The output pin delivers the timer's output signal.
4. Reset: This active-low pin resets the flip-flop, turning off the output. If not used, it should be connected to VCC.
5. Control Voltage (CV): Allows adjustment of the threshold and trigger levels. For standard operation, it is usually connected to a capacitor to ground.
6. Threshold: When the voltage on this pin exceeds 2/3 VCC, it resets the flip-flop, turning the output low.
7. Discharge: This pin is connected to the collector of a transistor, used to discharge a capacitor in timing applications.
8. VCC: The positive supply voltage pin, typically ranging from 4.5V to 15V.
The NE555PS can be used for various applications, including monostable and astable configurations.
