CD74HC137E datasheet by Texas Instruments

CD74HC137E Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the CD74HC137E?
  The CD74HC137E can operate at frequencies up to 25 MHz.
• How do I ensure that the CD74HC137E is properly powered?
  The CD74HC137E 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 CD74HC137E?
  The propagation delay time for the CD74HC137E is typically around 10 ns to 15 ns, depending on the operating frequency and voltage.
• Can I use the CD74HC137E in a 3.3 V system?
  Yes, the CD74HC137E is compatible with 3.3 V systems, but ensure that the input signals are within the recommended voltage range of 0.8 V to 2.4 V.
• How do I handle the enable inputs (E1, E2, E3, and E4) for proper operation?
  The enable inputs must be connected to a valid logic level (either VCC or GND) to ensure proper operation. Leaving them floating can cause unpredictable behavior.
