The LM555CMM is a popular timer IC with a total of 8 pins. Here are the pin assignments and their functions:
1. GND: Ground reference (0V).
2. Trigger (pin 2): Active low input that triggers the timing interval by detecting a negative-going pulse.
3. Output (pin 3): Provides the timed output signal; goes high during the timing interval.
4. Reset (pin 4): Active low input to reset the timer; can be used to stop the timing cycle.
5. Control Voltage (pin 5): Used to adjust the timing intervals; typically connected to ground with a capacitor for stability.
6. Threshold (pin 6): Compares the voltage at this pin with the internal reference voltage (1/3 Vcc) to reset the timer.
7. Discharge (pin 7): Connected to a transistor that discharges the timing capacitor when the output goes low.
8. VCC (pin 8): Supply voltage (typically +5V to +15V).
The LM555 can be configured in astable, monostable, and bistable modes for various timing applications.
