CD4521BEE4 Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for CD4521BEE4?
  The recommended operating voltage range for CD4521BEE4 is 4.5V to 5.5V, although it can operate from 3V to 18V with reduced performance.
• How do I handle the unused inputs on the CD4521BEE4?
  Unused inputs on the CD4521BEE4 should be tied to VCC or GND to prevent floating inputs, which can cause unpredictable behavior.
• What is the maximum frequency of operation for the CD4521BEE4?
  The maximum frequency of operation for the CD4521BEE4 is typically around 10 MHz, but this can vary depending on the specific application and operating conditions.
• Can I use the CD4521BEE4 in a 3.3V system?
  Yes, the CD4521BEE4 can be used in a 3.3V system, but the output voltage levels may not be as high as those in a 5V system, and the device may not meet the specified propagation delay times.
• How do I ensure the CD4521BEE4 is properly powered?
  Ensure the CD4521BEE4 is properly powered by providing a stable power supply with minimal noise and ripple, and by using decoupling capacitors (e.g., 0.1 μF) close to the device.
