CD74HC147M datasheet by Texas Instruments

CD74HC147M Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the CD74HC147M?
  The maximum frequency of operation for the CD74HC147M is 25 MHz.
• How do I ensure that the CD74HC147M is properly powered?
  The CD74HC147M requires a single power supply voltage (VCC) of 2.0 V to 6.0 V. Ensure that the power supply is stable and within the recommended operating range.
• What is the propagation delay time for the CD74HC147M?
  The propagation delay time (tpd) for the CD74HC147M is typically 15 ns, but can vary depending on the operating conditions and load capacitance.
• Can I use the CD74HC147M in a 3.3V system?
  Yes, the CD74HC147M can operate in a 3.3V system, but ensure that the input signals are compatible with the device's input voltage range (Vih and Vil).
• How do I handle the unused inputs on the CD74HC147M?
  Unused inputs on the CD74HC147M should be tied to a valid logic level (either VCC or GND) to prevent floating inputs and ensure proper device operation.
