CD74HC85EE4 Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the CD74HC85EE4 can handle?
  The CD74HC85EE4 can handle clock frequencies up to 30 MHz.
• How do I ensure that the CD74HC85EE4 is properly powered?
  The CD74HC85EE4 requires a single 2V to 6V power supply, and it's recommended to use a decoupling capacitor of 0.1uF to 1uF between VCC and GND to ensure proper power supply decoupling.
• What is the propagation delay of the CD74HC85EE4?
  The propagation delay of the CD74HC85EE4 is typically around 10ns to 20ns, depending on the operating voltage and temperature.
• Can I use the CD74HC85EE4 in a 3.3V system?
  Yes, the CD74HC85EE4 is compatible with 3.3V systems, but it's recommended to check the voltage tolerance of the specific device and ensure that it meets the system's voltage requirements.
• How do I handle the output enable (OE) pin of the CD74HC85EE4?
  The output enable (OE) pin should be connected to a logic low (GND) to enable the outputs, and to a logic high (VCC) to disable the outputs. It's recommended to use a pull-down resistor to ensure that the OE pin is properly biased.
