LM556CM datasheet by Texas Instruments

LM556CM Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the LM556CM?
  The maximum power dissipation of the LM556CM is 625mW, which is calculated based on the maximum junction temperature (Tj) of 150°C and the thermal resistance (RθJA) of 160°C/W.
• Can I use the LM556CM as a voltage regulator?
  No, the LM556CM is a dual timer, not a voltage regulator. It's designed to generate timing signals, not regulate voltage. If you need a voltage regulator, consider using a dedicated voltage regulator IC like the 78L05 or LM317.
• How do I calculate the timing period of the LM556CM?
  The timing period of the LM556CM can be calculated using the formula: T = 1.1 * R * C, where R is the resistance in ohms and C is the capacitance in farads. This formula assumes a standard 555 timer configuration.
• Can I use the LM556CM as a crystal oscillator?
  No, the LM556CM is not designed to be used as a crystal oscillator. It's a timer IC, not a crystal oscillator. If you need a crystal oscillator, consider using a dedicated crystal oscillator IC like the MC12060 or the CD4060.
• What is the minimum and maximum operating voltage of the LM556CM?
  The minimum operating voltage of the LM556CM is 4.5V, and the maximum operating voltage is 16V. Operating the IC outside of this range may affect its performance or damage the device.
