CD74AC253M datasheet by Texas Instruments

CD74AC253M Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the CD74AC253M?
  The maximum operating frequency of the CD74AC253M is 100 MHz, but it can vary depending on the specific application and operating conditions.
• How do I handle the power-up and power-down sequencing of the CD74AC253M?
  It is recommended to power up the VCC pin before the input signals and power down the VCC pin after the input signals to prevent unwanted output states.
• What is the recommended termination scheme for the CD74AC253M?
  The recommended termination scheme for the CD74AC253M is to use a 50-ohm termination resistor at the output of each channel to prevent signal reflections and ensure signal integrity.
• Can I use the CD74AC253M in a 3.3V system?
  Yes, the CD74AC253M can operate in a 3.3V system, but the input and output voltage levels may need to be adjusted accordingly to ensure proper operation.
• How do I handle the thermal management of the CD74AC253M?
  The CD74AC253M is a surface-mount device, and thermal management can be handled through proper PCB design, thermal vias, and heat sinks if necessary.
