CD74HCT126M96 datasheet by Texas Instruments

CD74HCT126M96 Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for CD74HCT126M96?
  The recommended operating voltage range for CD74HCT126M96 is 4.5V to 5.5V.
• How do I ensure signal integrity when using CD74HCT126M96 in a high-speed application?
  To ensure signal integrity, use a low-impedance PCB design, keep signal traces short, and use termination resistors if necessary. Also, consider using a clock signal with a rise time of 1ns or slower to minimize reflections.
• Can I use CD74HCT126M96 in a 3.3V system?
  While CD74HCT126M96 is specified for 5V operation, it can be used in a 3.3V system with some limitations. However, the output voltage will be reduced, and the device may not meet the specified propagation delay and output current.
• How do I handle power sequencing when using CD74HCT126M96 with other devices?
  To avoid latch-up or other issues, ensure that the power supply to CD74HCT126M96 is turned on after the power supplies to other devices in the system. Also, consider using a power-on reset circuit to ensure a clean startup.
• What is the maximum clock frequency supported by CD74HCT126M96?
  The maximum clock frequency supported by CD74HCT126M96 is 30MHz. However, this may vary depending on the specific application and PCB design.
