SN74LVCR162245DL datasheet by Texas Instruments

SN74LVCR162245DL Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74LVCR162245DL?
  The maximum operating frequency of the SN74LVCR162245DL is 250 MHz, but it can vary depending on the specific application and operating conditions.
• How do I ensure signal integrity when using the SN74LVCR162245DL?
  To ensure signal integrity, it's recommended to use a low-impedance PCB design, minimize trace lengths, and use termination resistors as needed. Additionally, follow proper PCB layout guidelines and use signal integrity analysis tools to simulate and optimize the design.
• Can I use the SN74LVCR162245DL in a 3.3V system?
  Yes, the SN74LVCR162245DL is compatible with 3.3V systems, but it's essential to ensure that the input voltage does not exceed the maximum rating of 4.6V. Additionally, the output voltage may need to be level-shifted to match the 3.3V system requirements.
• How do I handle power sequencing when using the SN74LVCR162245DL?
  To ensure proper operation, it's recommended to sequence the power supplies to the SN74LVCR162245DL in the following order: VCC, then VCCA, and finally VIN. This helps prevent latch-up and ensures reliable operation.
• What is the recommended termination scheme for the SN74LVCR162245DL?
  The recommended termination scheme for the SN74LVCR162245DL is to use a series terminator (Rs) of 33-50 ohms, along with a parallel terminator (Rt) of 50-100 ohms. This helps to reduce signal reflections and improve signal integrity.
