TLC555QDR Frequently Asked Questions (FAQ)

  • The maximum operating frequency of TLC555QDR is 2.1 MHz, but it can be limited by the external components and the application.

  • The choice of resistor and capacitor values depends on the desired frequency and duty cycle of the output signal. A good starting point is to use the formulas provided in the datasheet, and then adjust the values based on the specific application requirements.

  • The control voltage pin (pin 5) is used to adjust the threshold voltage of the internal comparator, which in turn affects the output frequency and duty cycle. It can be used to modulate the output frequency or to synchronize the oscillator with an external signal.

  • No, the TLC555QDR is a timer IC and not a voltage regulator. It is not designed to regulate voltage and should not be used as a substitute for a voltage regulator.

  • To ensure reliable startup, make sure to provide a stable power supply, use a bypass capacitor on the power supply pin, and ensure that the timing capacitor is fully discharged before startup.
