SN74ABT2240ADWR datasheet by Texas Instruments

SN74ABT2240ADWR Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74ABT2240ADWR?
  The maximum operating frequency of the SN74ABT2240ADWR is 100 MHz, but it can vary depending on the system design and capacitive loading.
• How do I ensure signal integrity when using the SN74ABT2240ADWR?
  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 SN74ABT2240ADWR in a 3.3V system?
  Yes, the SN74ABT2240ADWR 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 SN74ABT2240ADWR?
  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 SN74ABT2240ADWR?
  The recommended termination scheme is to use a series terminator (Rs) of 22-33 ohms, and a parallel terminator (Rt) of 47-68 ohms, depending on the system requirements and capacitive loading.
