SN74ACT244PWRE4 Frequently Asked Questions (FAQs)

  • The maximum operating frequency of the SN74ACT244PWRE4 is 100 MHz, but it can vary depending on the system design and capacitive load.
  • The SN74ACT244PWRE4 has a thermal pad on the bottom of the package, which should be connected to a thermal plane on the PCB to dissipate heat. A thermal via or a copper pour can be used to connect the thermal pad to the thermal plane.
  • The recommended PCB layout for the SN74ACT244PWRE4 includes using a solid ground plane, minimizing trace lengths and impedance, and using bypass capacitors to decouple the power supply. A 4-layer PCB with a dedicated power plane and a dedicated ground plane is recommended.
  • Yes, the SN74ACT244PWRE4 can be used in a 3.3V system, but the input voltage should not exceed 3.6V to ensure reliable operation. Additionally, the output voltage will be limited to 3.3V, which may affect the signal integrity.
  • To ensure signal integrity with the SN74ACT244PWRE4, use a controlled impedance PCB, minimize trace lengths and impedance, and use termination resistors or series resistors to match the impedance of the transmission line. Additionally, use a clock signal with a rise time of less than 1 ns to prevent signal distortion.
