CD74HCT151M96 datasheet by Texas Instruments

CD74HCT151M96 Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the CD74HCT151M96?
  The maximum operating frequency of the CD74HCT151M96 is 30 MHz, but it can vary depending on the specific application and operating conditions.
• How do I ensure signal integrity when using the CD74HCT151M96?
  To ensure signal integrity, use proper PCB layout techniques, such as keeping signal traces short and away from noise sources, using termination resistors, and minimizing impedance mismatches.
• Can I use the CD74HCT151M96 with 3.3V or 5V logic levels?
  The CD74HCT151M96 is designed to operate with 4.5V to 5.5V supply voltage, but it can tolerate 3.3V logic levels on the input pins. However, the output voltage levels will still be 5V.
• How do I handle power sequencing when using the CD74HCT151M96?
  To avoid latch-up or other issues, ensure that the power supply voltage (VCC) is applied before the input signals, and that the input signals are stable before the clock signal is applied.
• What is the maximum current that the CD74HCT151M96 can sink or source?
  The CD74HCT151M96 can sink or source up to 6mA per output pin, but it's recommended to limit the current to 4mA or less to ensure reliable operation.
