ISL81487LIPZ - 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

ISL81487LIPZ Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the analog and digital grounds separate and connect them at a single point. Use a common mode filter or a ferrite bead to reduce EMI.
  • Follow the power-up sequence outlined in the datasheet. Ensure that the VCC pin is powered up before the VDD pin. Also, configure the device by setting the correct register values and mode settings according to the application requirements.
  • The device has a maximum junction temperature of 150°C. Ensure good airflow around the device, and consider using a heat sink or thermal pad to dissipate heat. Avoid blocking the airflow around the device.
  • Use a logic analyzer or oscilloscope to capture the signal waveforms and debug the issue. Check the device's configuration and register settings. Consult the datasheet and application notes for troubleshooting guidelines.
  • The device has built-in ESD protection diodes. However, it's still important to follow proper ESD handling procedures during assembly and handling. For latch-up prevention, ensure that the device is powered up and configured correctly, and avoid voltage spikes or transients on the power pins.
