ISL8491EIBZ-T - Renesas Electronics

Description: The ISL8488E, ISL8489E, ISL8490E, ISL8491E devices are ESD protected, BiCMOS, 5V powered, single transceivers that meet both the RS-485 and RS-422 standards for balanced communication. Each driver output and receiver input is protected against ±15kV ESD strikes, without latch-up. Unlike competitive versions, these Intersil devices are specified for 10% tolerance supplies (4. 5V to 5. 5V). These devices are configured for full duplex (separate Rx input and Tx output pins) applications, so they are ideal for

ISL8491EIBZ-T Frequently Asked Questions (FAQs)

  • A good PCB layout for the ISL8491EIBZ-T involves keeping the analog and digital grounds separate, using a solid ground plane, and minimizing the length of the traces between the IC and the capacitors. A 4-layer PCB with a dedicated ground plane is recommended.
  • To ensure the stability of the output voltage, it is essential to use the recommended output capacitor values and types, and to place them as close to the IC as possible. Additionally, the input capacitor should be selected based on the input voltage and current requirements.
  • The ISL8491EIBZ-T is rated for operation over a temperature range of -40°C to +125°C. However, the maximum ambient temperature range may vary depending on the specific application and the thermal design of the system.
  • Yes, the ISL8491EIBZ-T is suitable for use in high-reliability and automotive applications. It is AEC-Q100 qualified and meets the requirements for automotive-grade components.
  • To troubleshoot issues with the ISL8491EIBZ-T, start by checking the input voltage, output voltage, and current consumption. Verify that the PCB layout and component selection meet the recommended guidelines. Use an oscilloscope to check for oscillations or noise on the output voltage. If the issue persists, consult the datasheet and application notes for further guidance.
