SN74LVC2244APWRE4 datasheet by Texas Instruments

SN74LVC2244APWRE4 Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the SN74LVC2244APWRE4?
  The recommended operating voltage range for the SN74LVC2244APWRE4 is 1.65V to 3.6V.
• How do I ensure signal integrity when using the SN74LVC2244APWRE4 in a high-speed application?
  To ensure signal integrity, use a low-impedance PCB design, keep signal traces short, and use termination resistors as needed. Also, consider using a signal integrity analysis tool to simulate and optimize your design.
• Can I use the SN74LVC2244APWRE4 in a 5V system?
  While the SN74LVC2244APWRE4 is rated for 3.6V maximum, it can tolerate 5V inputs with some limitations. However, it's not recommended to operate the device at 5V continuously, as it may affect reliability and lifespan. If you need to interface with 5V logic, consider using a level translator or voltage regulator.
• How do I handle power sequencing when using multiple SN74LVC2244APWRE4 devices in a system?
  To avoid latch-up or other issues, ensure that the power supply voltage (VCC) is applied to all devices simultaneously, or sequence the power-on in a way that ensures the input signals are stable before the device is enabled.
• What is the maximum clock frequency supported by the SN74LVC2244APWRE4?
  The maximum clock frequency supported by the SN74LVC2244APWRE4 is 100 MHz, but this can vary depending on the specific application, PCB design, and operating conditions. Consult the datasheet and application notes for more information.
