SN74AHC244MDWREP datasheet by Texas Instruments

SN74AHC244MDWREP Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74AHC244MDWREP?
  The maximum operating frequency of the SN74AHC244MDWREP is 100 MHz, but it can vary depending on the output load and the system design.
• How do I ensure signal integrity when using the SN74AHC244MDWREP?
  To ensure signal integrity, use proper PCB design techniques such as impedance matching, signal routing, and decoupling. Also, consider using series termination resistors and/or parallel termination capacitors to reduce signal reflections and ringing.
• Can I use the SN74AHC244MDWREP in a 3.3V system?
  Yes, the SN74AHC244MDWREP is compatible with 3.3V systems. It has a wide operating voltage range of 2V to 5.5V, making it suitable for use in 3.3V systems.
• How do I handle power sequencing when using the SN74AHC244MDWREP?
  To avoid latch-up and ensure proper operation, ensure that the power supply voltage (VCC) is applied before the input signals. Also, ensure that the power supply voltage is stable and within the recommended operating range before applying input signals.
• What is the maximum current that the SN74AHC244MDWREP can sink or source?
  The SN74AHC244MDWREP can sink or source up to 24 mA of current per output pin. However, the total current drawn from the device should not exceed the recommended maximum current rating of 100 mA.
