Description

This reference design provides an isolated, 20-Mbps, 3.3-V to 5-V RS-485 interface using the ISO3086T isolated RS-485 transceiver and the TPS76350 high-accuracy linear regulator. This circuit achieves signal and power isolation and at the same time decreases board space and power consumption.

Features
  • 4000V peak isolation
  • 1/8 unit load - up to 256 nodes on a bus
  • Signaling rates up to 20Mbps
  • 50kV/us typical transient immunity
  • This reference design is orderable
