CD4543BM Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the CD4543BM is 4.5V to 15.5V.
  • To ensure proper biasing, connect the VCC pin to a stable voltage source, and decouple it with a 0.1uF capacitor to ground. Also, ensure the input signals are within the recommended voltage range.
  • The maximum frequency of operation for the CD4543BM is 100 kHz.
  • The CD4543BM has an open-drain output, so it can sink current but not source it. To drive a load, connect a pull-up resistor to the output pin and a voltage source (e.g., VCC).
  • The inhibit pin (INH) is used to disable the oscillator output when it is high. This can be useful for power-saving or synchronization applications.
