SN74CBTD3384PWRG4 datasheet by Texas Instruments

SN74CBTD3384PWRG4 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the SN74CBTD3384PWRG4 to minimize signal integrity issues?
  Texas Instruments recommends following the PCB layout guidelines in the application note 'AN-1149 PCB Layout Guidelines for TI FET Bus Switches' to minimize signal integrity issues. This includes keeping signal traces short, using impedance-controlled traces, and avoiding vias under the device.
• How do I ensure the SN74CBTD3384PWRG4 is properly powered and bypassed?
  The SN74CBTD3384PWRG4 requires a 1.8-V to 5.5-V power supply. Ensure proper power supply decoupling by placing a 0.1-μF ceramic capacitor between VCC and GND, and a 10-μF bulk capacitor between VCC and GND. Additionally, follow the power supply sequencing guidelines in the datasheet to prevent latch-up.
• What is the maximum data rate that the SN74CBTD3384PWRG4 can support?
  The SN74CBTD3384PWRG4 can support data rates up to 500 Mbps, making it suitable for high-speed applications such as USB, SATA, and PCIe.
• How do I handle hot-swapping or live-insertion with the SN74CBTD3384PWRG4?
  The SN74CBTD3384PWRG4 is designed to support hot-swapping and live-insertion. However, to ensure reliable operation, follow the guidelines in the application note 'AN-1111 Hot-Swapping and Live-Insertion of TI FET Bus Switches'. This includes using a power sequencing circuit and ensuring that the device is properly powered down before removal.
• What is the ESD protection level of the SN74CBTD3384PWRG4?
  The SN74CBTD3384PWRG4 has an ESD protection level of ±2 kV human-body model (HBM) and ±1 kV charged-device model (CDM), making it suitable for use in applications where ESD protection is critical.
