CD4543BE Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the CD4543BE?
  The recommended operating voltage range for the CD4543BE is 4.5V to 15.5V.
• How do I ensure the CD4543BE is properly powered on and off?
  To ensure proper power-on and power-off, the CD4543BE requires a monotonic power supply ramp-up and ramp-down. A minimum of 1ms is recommended for power-on and power-off times.
• What is the maximum frequency of operation for the CD4543BE?
  The maximum frequency of operation for the CD4543BE is 100 kHz.
• How do I handle the output stage of the CD4543BE?
  The output stage of the CD4543BE is an open-drain configuration, which means it can sink current but not source current. An external pull-up resistor is required to pull the output high.
• What is the purpose of the inhibit input (INH) on the CD4543BE?
  The inhibit input (INH) on the CD4543BE is used to disable the oscillator and output stages when high, allowing the device to enter a low-power standby mode.
