SN74HCT125DT datasheet by Texas Instruments

SN74HCT125DT Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the SN74HCT125DT?
  The maximum frequency of operation for the SN74HCT125DT is 40 MHz.
• Can I use the SN74HCT125DT in a 5V system?
  Yes, the SN74HCT125DT 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 output enable (OE) pin?
  The output enable (OE) pin is active-low, meaning it should be connected to GND to enable the outputs. Leaving it unconnected or connecting it to VCC will disable the outputs.
• What is the propagation delay of the SN74HCT125DT?
  The propagation delay of the SN74HCT125DT is approximately 10 ns.
• Can I use the SN74HCT125DT in a 3.3V system?
  No, the SN74HCT125DT is not compatible with 3.3V systems. It's designed to operate at 5V, and using it at 3.3V may result in unreliable operation or damage to the device.
