CD74HC85E datasheet by Texas Instruments

CD74HC85E Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the CD74HC85E?
  The maximum frequency of operation for the CD74HC85E is 25 MHz.
• How do I ensure that the CD74HC85E is properly powered?
  The CD74HC85E requires a power supply voltage (VCC) of 2.0 V to 6.0 V, and it is recommended to decouple the power supply with a 0.1 μF capacitor.
• What is the propagation delay time for the CD74HC85E?
  The propagation delay time for the CD74HC85E is typically 15 ns, but it can vary depending on the operating conditions and the specific application.
• Can the CD74HC85E be used in a 3.3 V or 5 V system?
  Yes, the CD74HC85E can be used in both 3.3 V and 5 V systems, as it is designed to operate over a wide range of power supply voltages.
• How do I handle the unused inputs on the CD74HC85E?
  Unused inputs on the CD74HC85E should be tied to a logic level (either VCC or GND) to prevent floating inputs and ensure proper operation.
