83947AYILN - Renesas Electronics

Description: The 83947I is a low skew, 1-to-9 LVCMOS Fanout Buffer. The low impedance LVCMOS/LVTTL outputs are designed to drive 50Ω series or parallel terminated transmission lines. The effective fanout can be increased from 9 to 18 byutilizing the ability of the outputs to drive two series terminated lines. Guaranteed output and part-to-part skew characteristics make the 83947I ideal for high performance, single ended applications that also require a limited output voltage.

83947AYILN Frequently Asked Questions (FAQs)

  • Renesas recommends a 4-layer PCB with a solid ground plane and thermal vias to dissipate heat efficiently. A minimum of 2 oz copper thickness is recommended for the power planes.
  • Renesas recommends using a thermal interface material (TIM) with a thermal conductivity of at least 1 W/m-K between the device and the heat sink. Ensure the heat sink is properly secured to the device.
  • Renesas recommends using a 10uF to 22uF X7R or X5R ceramic capacitor with a voltage rating of at least 25V. The capacitor should be placed as close to the VIN pin as possible.
  • Check the voltage on the VCC pin, ensure the input voltage is within the recommended range, and verify the power-good signal is not being pulled low by another device. Consult the datasheet for specific timing diagrams and voltage thresholds.
  • The maximum allowed voltage on the EN pin is 6V. Exceeding this voltage may damage the device. Ensure the voltage on the EN pin is within the recommended range of 0V to 5.5V.
