LM555CMX Frequently Asked Questions (FAQ)

  • The LM555CMX can operate from -40°C to 125°C, but the recommended operating temperature range is 0°C to 70°C for optimal performance.

  • No, the LM555CMX is a timer IC and not a voltage regulator. It's designed to generate a stable clock signal or oscillation, not to regulate voltage.

  • To ensure stable oscillation, use a high-quality capacitor (e.g., ceramic or film) for C1 and C2, and choose R1 and R2 values that provide a stable voltage divider. Also, ensure the power supply is clean and well-regulated.

  • The maximum output current of the LM555CMX is approximately 200mA, but it's recommended to keep the output current below 100mA for reliable operation.

  • Yes, the LM555CMX can be used as a crystal oscillator. Connect the crystal between pins 2 and 3, and use a capacitor (e.g., 22pF) between pin 2 and ground to ensure stable oscillation.
