CD74HC147PWR datasheet by Texas Instruments

CD74HC147PWR Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the CD74HC147PWR?
  The maximum frequency of operation for the CD74HC147PWR is 25 MHz.
• How do I ensure that the CD74HC147PWR is properly powered?
  To ensure proper power supply, connect VCC to a 2.0-V to 6.0-V power supply, and GND to the system ground. Decouple the power supply with a 0.1-μF capacitor.
• What is the maximum input voltage that the CD74HC147PWR can tolerate?
  The maximum input voltage that the CD74HC147PWR can tolerate is 6.5V, which is the absolute maximum rating.
• How do I handle the unused inputs of the CD74HC147PWR?
  Unused inputs should be tied to VCC or GND through a 1-kΩ resistor to prevent floating inputs and reduce power consumption.
• What is the propagation delay of the CD74HC147PWR?
  The propagation delay of the CD74HC147PWR is typically 10 ns, but it can vary depending on the operating conditions and load capacitance.
