ISL81487EIBZ-T - 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

ISL81487EIBZ-T Frequently Asked Questions (FAQs)

  • A good PCB layout for the ISL81487EIBZ-T involves keeping the analog and digital grounds separate, using a solid ground plane, and minimizing the length of the input and output traces. Additionally, it's recommended to place the device close to the power supply and use a low-ESR capacitor for decoupling.
  • To ensure stability, it's essential to follow the recommended operating conditions, such as input voltage, output current, and temperature range. Additionally, a minimum of 10uF capacitance is recommended for the output capacitor, and the device should be operated within the recommended frequency range.
  • The ISL81487EIBZ-T has a thermal shutdown feature that activates when the junction temperature exceeds 150°C. To prevent overheating, ensure good airflow, use a heat sink if necessary, and avoid operating the device at maximum power for extended periods.
  • To troubleshoot issues, start by verifying the input voltage, output voltage, and current. Check for proper PCB layout, decoupling, and thermal management. Use an oscilloscope to monitor the output voltage and current, and consult the datasheet for specific troubleshooting guidelines.
  • To minimize EMI, use a shielded enclosure, keep the device away from sensitive circuits, and use a common-mode choke or ferrite bead on the input and output lines. Additionally, ensure good PCB layout and decoupling to reduce radiated emissions.
