CD74HC4518E Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the CD74HC4518E?
  The maximum frequency of operation for the CD74HC4518E is 40 MHz, but it can vary depending on the specific application and operating conditions.
• How do I ensure proper power sequencing for the CD74HC4518E?
  To ensure proper power sequencing, the VCC pin should be powered up before the input signals, and the input signals should be stable before the clock signal is applied.
• What is the recommended operating voltage range for the CD74HC4518E?
  The recommended operating voltage range for the CD74HC4518E is 2V to 6V, with a typical operating voltage of 5V.
• How do I handle unused inputs on the CD74HC4518E?
  Unused inputs on the CD74HC4518E should be tied to a logic high or low level to prevent floating inputs, which can cause unpredictable behavior.
• What is the maximum output current of the CD74HC4518E?
  The maximum output current of the CD74HC4518E is 25mA per output pin, but it's recommended to limit the output current to 10mA or less to ensure reliable operation.
