The RS-485 QSOP Isolated Transceiver Evaluation Board provides a complete isolated RS-485 node using the world's isolated transceiver, the IL3085-1E. The board provides screw terminal and RJ45 connections, and demonstrates best layout practices.
Termination, pull-up, and pull-down resistors are easily changed to accommodate various fanouts and termination methods.
The transceiver delivers an exceptional 2.3 V differential output into a 54 Ohm load and data rates to 40 Mbps. The device is also compatible with 3.3 V input supplies, allowing interface to standard microcontrollers without additional level shifting.
The IL3022E is a cost-effective isolated 4 Mbps RS-422 full-duplex transceiver, compatible with 3.3 V or 5 V input logic. 7 kV bus ESD protection; 50 kV per microsecond transient immunity. 16-pin wide-body SOIC package with True 8™ mm creepage.
