CD74HC151M datasheet by Texas Instruments

CD74HC151M Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the CD74HC151M?
  The maximum frequency of operation for the CD74HC151M is 25 MHz.
• How do I ensure that the CD74HC151M is properly powered?
  The CD74HC151M requires a single 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 CD74HC151M?
  The propagation delay time for the CD74HC151M is typically 10 ns, but it can vary depending on the operating frequency and voltage.
• Can I use the CD74HC151M in a 3.3 V system?
  Yes, the CD74HC151M can operate in a 3.3 V system, but it is recommended to check the voltage tolerance of the device and ensure that it meets the system's voltage requirements.
• How do I handle the enable inputs (E1 and E2) for the CD74HC151M?
  The enable inputs (E1 and E2) must be connected to a valid logic level (either VCC or GND) to ensure proper operation of the device. Leaving them unconnected or floating can cause unpredictable behavior.
