SN74HCT244PWG4 Frequently Asked Questions (FAQ)

  • The maximum operating frequency of the SN74HCT244PWG4 is 50 MHz, but it can vary depending on the system design and capacitive load.

  • To ensure signal integrity, use a low-impedance PCB design, keep signal traces short, and use termination resistors if necessary. Also, ensure that the power supply is clean and well-regulated.

  • Yes, the SN74HCT244PWG4 is compatible with 5V systems, but it's recommended to use a voltage regulator to ensure a stable 4.5V to 5.5V supply voltage range.

  • The SN74HCT244PWG4 can sink or source up to 6mA per output, but it's recommended to limit the current to 4mA per output to ensure reliable operation.

  • To handle thermal issues, ensure good airflow around the device, use a heat sink if necessary, and avoid operating the device at maximum power dissipation for extended periods.
