CD74HCT153M datasheet by Texas Instruments

CD74HCT153M Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the CD74HCT153M?
  The maximum operating frequency of the CD74HCT153M is 30 MHz.
• Can I use the CD74HCT153M in a 5V system?
  Yes, the CD74HCT153M is compatible with 5V systems, but it's recommended to use a voltage regulator to ensure a stable 4.5V to 5.5V supply voltage.
• How do I handle the enable inputs (E1 and E2) when not in use?
  When not in use, the enable inputs (E1 and E2) should be tied to VCC or GND to prevent floating inputs, which can cause unpredictable behavior.
• What is the propagation delay of the CD74HCT153M?
  The propagation delay of the CD74HCT153M is typically around 10 ns, but it can vary depending on the operating conditions and load capacitance.
• Can I use the CD74HCT153M in a 3.3V system?
  No, the CD74HCT153M is not compatible with 3.3V systems, as it's designed to operate at 4.5V to 5.5V. For 3.3V systems, consider using the CD74ACT153M or other 3.3V-compatible devices.
