Application Notes
- Isolated RS-485 Reference DesignPDF, 80 Kb, File published: Oct 28, 2009
This design note presents the reference designs of isolated RS-485 nodes, using bus voltages of 3.3 V and 5 V. Various transceivers are used to satisfy the requirements for low, medium, and high data rates, as well as to accommodate the need for half- and full-duplex operation. - Digital Isolator Design Guide (Rev.
