CD74HC4514ENE4 Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the CD74HC4514?
  The maximum frequency of operation for the CD74HC4514 is 25 MHz, but it can vary depending on the supply voltage and operating conditions.
• How do I ensure proper power sequencing for the CD74HC4514?
  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 CD74HC4514?
  The recommended operating voltage range for the CD74HC4514 is 2V to 6V, but it can operate down to 1.5V with reduced performance.
• How do I handle unused inputs on the CD74HC4514?
  Unused inputs on the CD74HC4514 should be tied to a logic level (either VCC or GND) to prevent floating inputs and ensure proper operation.
• Is the CD74HC4514 compatible with 5V and 3.3V logic levels?
  Yes, the CD74HC4514 is compatible with both 5V and 3.3V logic levels, making it suitable for use in mixed-voltage systems.
