LMC555CMX/NOPB Typical application Circuitry

LMC555CMX/NOPB

A model from the LMC555 family, the LMC555CMX/NOPB is a CMOS take on the traditional 555 timer integrated circuit. This series is notable for its low power consumption and wide voltage range, making it particularly suitable for battery-operated and energy-efficient applications.

1. Ground (Pin 1): Connect this pin to the circuit's ground (0V).

2. Trigger (Pin 2): This pin initiates the timing sequence when the voltage drops below 1/3 of the supply voltage. It's typically connected to an RC (resistor-capacitor) network for setting the timing interval.

3. Output (Pin 3): This pin delivers the output signal from the timer. It can source or sink significant current, making it capable of driving various loads, including TTL inputs.

4. Reset (Pin 4): Applying a low signal to this pin resets the timer. It may be linked to the positive supply voltage for continuous operation. If not used, it should be tied to Vcc to avoid unintentional resets.

5. Control Voltage (Pin 5): This pin allows for external modulation of the timer's internal voltage reference. If not used, it's typically connected to ground through a small capacitor (e.g., 0.01 µF) to provide noise immunity.

6. Threshold (Pin 6): This pin connects to an internal comparator that resets the timer. It is usually part of the same RC network as the trigger pin.

7. Discharge (Pin 7): When the output is low, this open-collector output is connected to ground. It is typically used to discharge the capacitor in the RC network in astable mode.

8. Supply Voltage (Vcc) (Pin 8): This pin is connected to the positive supply voltage, which should be within the range specified for the LMC555CMX/NOPB.

9. Decoupling Capacitor: A decoupling capacitor (like 0.1 µF) between Vcc and Ground is recommended to stabilize the power supply and filter out noise.

10. Reset Pin Functionality: If not using the reset function, tie Pin 4 to Vcc to prevent accidental resets.

11. Control Voltage Stabilization: If external control of the threshold and trigger levels is unnecessary, connect a capacitor from Pin 5 to Ground to stabilize the control voltage.

12. Timing Component Selection: Choose the resistor and capacitor values in the RC network connected to Pins 2 and 6 carefully, as they determine the timing intervals of the LMC555CMX/NOPB's operation.

The LMC555CMX/NOPB, part of the LMC555 series, is a versatile timer IC suitable for a wide range of applications, including timing, pulse generation, and oscillator circuits. Its efficiency and low power consumption make it an excellent choice for various electronic designs.
