SN74ABT18502PM datasheet by Texas Instruments

SN74ABT18502PM Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74ABT18502PM?
  The maximum operating frequency of the SN74ABT18502PM is 100 MHz, but it can vary depending on the system design and capacitive loading.
• How do I ensure signal integrity when using the SN74ABT18502PM?
  To ensure signal integrity, use controlled impedance PCB traces, minimize trace lengths, and use termination resistors as recommended in the datasheet. Additionally, consider using a signal integrity analysis tool to simulate and optimize your design.
• Can I use the SN74ABT18502PM in a 3.3V system?
  Yes, the SN74ABT18502PM is compatible with 3.3V systems, but ensure that the input voltage (VCC) is within the recommended range of 2.7V to 3.6V. Also, note that the output voltage levels may not be fully compliant with 3.3V logic levels.
• How do I handle power sequencing when using the SN74ABT18502PM?
  To avoid latch-up or other issues, ensure that the power supply voltage (VCC) is applied before the input signals. Also, consider using a power sequencing controller or a voltage supervisor to ensure proper power-up and power-down sequences.
• What is the recommended termination scheme for the SN74ABT18502PM?
  The recommended termination scheme for the SN74ABT18502PM is a series terminator (Rs) of 22-33 ohms, followed by a parallel terminator (Rt) of 50-75 ohms. However, the optimal termination scheme may vary depending on the system design and signal frequencies.
