SN74ABT2244ADBR datasheet by Texas Instruments

SN74ABT2244ADBR Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74ABT2244ADBR?
  The maximum operating frequency of the SN74ABT2244ADBR is 100 MHz, but it can vary depending on the system design and capacitive loading.
• How do I ensure signal integrity when using the SN74ABT2244ADBR?
  To ensure signal integrity, use proper PCB layout techniques, such as minimizing trace length, using impedance-controlled traces, and adding termination resistors as needed. Also, follow the recommended operating conditions and input/output capacitance guidelines.
• Can I use the SN74ABT2244ADBR in a 3.3V system?
  Yes, the SN74ABT2244ADBR is compatible with 3.3V systems, but ensure that the input voltage (VCC) is within the recommended range of 4.5V to 5.5V. The output voltage will be compatible with 3.3V systems.
• How do I handle power sequencing when using the SN74ABT2244ADBR?
  To avoid latch-up or other issues, ensure that the power supply (VCC) is applied before the input signals, and that the input signals are stable before the clock signal is applied.
• What is the recommended termination scheme for the SN74ABT2244ADBR?
  The recommended termination scheme for the SN74ABT2244ADBR is a series terminator (Rs) of 22-33 ohms, followed by a parallel terminator (Rt) of 47-68 ohms to VCC or GND, depending on the system requirements.
