CD74HC123EE4 Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the CD74HC123EE4?
  The recommended operating voltage range for the CD74HC123EE4 is 2V to 6V, with a typical voltage of 5V.
• How do I handle the unused inputs on the CD74HC123EE4?
  Unused inputs on the CD74HC123EE4 should be tied to a logic level (VCC or GND) to prevent floating inputs and ensure proper device operation.
• What is the maximum clock frequency that the CD74HC123EE4 can handle?
  The maximum clock frequency that the CD74HC123EE4 can handle is 10 MHz, but this can vary depending on the operating voltage and load capacitance.
• Can I use the CD74HC123EE4 in a 3.3V system?
  Yes, the CD74HC123EE4 can be used in a 3.3V system, but the output voltage will be limited to 3.3V, and the device may not be able to drive as much current as it would at 5V.
• How do I ensure that the CD74HC123EE4 is properly powered up and initialized?
  To ensure proper power-up and initialization, the CD74HC123EE4 should be powered up slowly (dv/dt < 10V/μs) and the inputs should be held in a valid state until the power supply has reached a stable level.
