ISL8487EIBZ - Renesas Electronics

Description: The ISL8487E, ISL81487L, and ISL81487E RS-485/RS-422 devices are ESD protected, fractional unit load (UL), BiCMOS, 5V powered, single transceivers that meet both the RS-485 and RS-422 standards for balanced communication. Each driver output/receiver input is protected against ±15kV ESD strikes without latch-up. Unlike competitive devices, this device family is specified for 10% tolerance supplies (4. 5V to 5. 5V). All devices present a 1/8 unit load to the RS-485 bus, which allows up to 256 transceivers on

ISL8487EIBZ Frequently Asked Questions (FAQs)

  • A good PCB layout for the ISL8487EIBZ involves keeping the analog and digital grounds separate, using a solid ground plane, and minimizing the length of the traces between the device and the capacitors. A 4-layer PCB with a dedicated ground plane is recommended.
  • To ensure proper power-up and power-down of the ISL8487EIBZ, follow the recommended power-up sequence: VCC, then VDD, then EN. For power-down, follow the reverse sequence. Also, ensure that the input voltage ramps up and down slowly to prevent latch-up.
  • The ISL8487EIBZ has a maximum junction temperature of 150°C. To ensure reliable operation, keep the device temperature below 125°C. Use thermal vias and a heat sink if necessary, and ensure good airflow around the device.
  • To troubleshoot issues with the ISL8487EIBZ, start by checking the power supply voltages, then verify the input and output signals using an oscilloscope. Check for proper termination, and ensure that the device is properly configured and initialized.
  • The ISL8487EIBZ has built-in ESD protection, but it's still important to follow proper ESD handling procedures when handling the device. Use an ESD wrist strap or mat, and ensure that the device is stored in an ESD-safe environment.
