SN74HCT244DBR datasheet by Texas Instruments

SN74HCT244DBR Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74HCT244DBR?
  The maximum operating frequency of the SN74HCT244DBR is 40 MHz.
• Can I use the SN74HCT244DBR in a 5V system?
  Yes, the SN74HCT244DBR is compatible with 5V systems, but it's recommended to use a voltage regulator to ensure a stable 5V supply.
• How do I handle the heat dissipation of the SN74HCT244DBR?
  The SN74HCT244DBR has a thermal pad on the bottom of the package. Ensure good thermal contact between the thermal pad and a heat sink or a metal plate on the PCB to dissipate heat effectively.
• What is the recommended PCB layout for the SN74HCT244DBR?
  Use a 4-layer PCB with a solid ground plane and a separate power plane. Keep the signal traces short and away from the power planes to minimize noise and crosstalk.
• Can I use the SN74HCT244DBR in a high-temperature environment?
  The SN74HCT244DBR is rated for operation up to 85°C. However, it's recommended to derate the device's performance and consider using a heat sink or a thermal management system for high-temperature applications.
