CD74HCT125E datasheet by Texas Instruments

CD74HCT125E Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for CD74HCT125E?
  The maximum frequency of operation for CD74HCT125E is 40 MHz.
• Can I use CD74HCT125E in a 5V system?
  Yes, CD74HCT125E is compatible with 5V systems, but it's recommended to use a voltage regulator to ensure a stable 5V supply.
• How do I handle the enable pins (1E, 2E, 3E, and 4E) in CD74HCT125E?
  The enable pins (1E, 2E, 3E, and 4E) are active-low, meaning they need to be connected to GND to enable the corresponding buffer. Connect them to VCC to disable the buffer.
• What is the propagation delay of CD74HCT125E?
  The propagation delay of CD74HCT125E is typically around 10-15 ns, but it can vary depending on the operating conditions and load capacitance.
• Can I use CD74HCT125E as a level shifter?
  Yes, CD74HCT125E can be used as a level shifter, but it's not recommended as it's not designed for level shifting. Instead, use a dedicated level shifter IC like the TXS0108E.
