SN74HCT244APWR datasheet by Texas Instruments

SN74HCT244APWR Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74HCT244APWR?
  The maximum operating frequency of the SN74HCT244APWR is 50 MHz, but it can vary depending on the system design and capacitive loading.
• How do I handle the power-up and power-down sequencing of the SN74HCT244APWR?
  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 operating voltage range for the SN74HCT244APWR?
  The recommended operating voltage range for the SN74HCT244APWR is 4.5V to 5.5V, but it can operate down to 4V with reduced performance.
• How do I ensure signal integrity when using the SN74HCT244APWR in a high-speed design?
  Use proper PCB layout techniques, such as impedance matching, signal termination, and shielding, to minimize signal reflections and crosstalk.
• Can I use the SN74HCT244APWR in a 3.3V system?
  Yes, the SN74HCT244APWR can be used in a 3.3V system, but the output voltage will be limited to 3.3V, and the input voltage threshold will be lower than the typical 2V for a 5V system.
