SN74AHC244QDWRG4 datasheet by Texas Instruments

SN74AHC244QDWRG4 Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74AHC244QDWRG4?
  The maximum operating frequency of the SN74AHC244QDWRG4 is 100 MHz, but it can vary depending on the system design and capacitive load.
• How do I ensure signal integrity when using the SN74AHC244QDWRG4?
  To ensure signal integrity, use a low-impedance PCB design, keep signal traces short, and use termination resistors if necessary. Also, follow the recommended layout guidelines in the datasheet.
• Can I use the SN74AHC244QDWRG4 in a 3.3V system?
  Yes, the SN74AHC244QDWRG4 is compatible with 3.3V systems, but ensure that the input voltage (VCC) is within the recommended range of 2.0V to 5.5V.
• How do I handle power sequencing when using the SN74AHC244QDWRG4?
  To avoid latch-up or damage, ensure that the power supply (VCC) is applied before the input signals, and that the input signals are stable before the power supply is applied.
• What is the recommended pull-up/pull-down resistor value for the SN74AHC244QDWRG4?
  The recommended pull-up/pull-down resistor value depends on the system design and capacitive load. A typical value is 1 kΩ to 10 kΩ, but it may need to be adjusted based on the specific application.
