CD74HC251M96 Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the CD74HC251M96?
  The maximum operating frequency of the CD74HC251M96 is 25 MHz, but it can vary depending on the supply voltage and load capacitance.
• How do I ensure signal integrity when using the CD74HC251M96?
  To ensure signal integrity, use a low-impedance output driver, minimize trace lengths, and use proper termination and decoupling techniques.
• Can I use the CD74HC251M96 in a 5V system?
  Yes, the CD74HC251M96 can operate from 2V to 6V, making it suitable for 5V systems. However, ensure that the input signals are within the recommended voltage range.
• What is the propagation delay of the CD74HC251M96?
  The propagation delay of the CD74HC251M96 is typically around 10-15 ns, but it can vary depending on the supply voltage, temperature, and load capacitance.
• How do I handle power-up and power-down sequencing with the CD74HC251M96?
  To avoid latch-up and ensure proper operation, ensure that the power supply voltage (VCC) is applied before the input signals, and that the input signals are stable before the output enable (OE) is asserted.
