SN74LVC2244ADBQR datasheet by Texas Instruments

SN74LVC2244ADBQR Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74LVC2244ADBQR?
  The maximum operating frequency of the SN74LVC2244ADBQR is 100 MHz, but it can vary depending on the load capacitance and the output current.
• How do I ensure signal integrity when using the SN74LVC2244ADBQR in a high-speed application?
  To ensure signal integrity, use a low-impedance PCB design, keep the signal traces short, and use termination resistors or series resistors to reduce reflections and ringing.
• Can I use the SN74LVC2244ADBQR in a 3.3V system, and if so, what are the power supply requirements?
  Yes, the SN74LVC2244ADBQR can operate in a 3.3V system. The recommended power supply voltage is 3.3V ± 0.3V, and the device can tolerate a maximum voltage of 3.6V.
• What is the maximum output current that the SN74LVC2244ADBQR can sink or source?
  The maximum output current that the SN74LVC2244ADBQR can sink or source is 24 mA per output, but it's recommended to limit the output current to 12 mA per output to ensure reliable operation.
• How do I handle thermal issues when using the SN74LVC2244ADBQR in a high-power application?
  To handle thermal issues, ensure good thermal conductivity between the device and the PCB, use a heat sink if necessary, and keep the device away from other heat sources.
