9.1 Overview

The ISO1500 device is an isolated RS-485/RS-422 transceiver designed to operate in harsh industrial environments. This device supports data transmissions up to 1 Mbps. The ISO1500 device has a 3-channel digital isolator and an RS-485 transceiver in an ultra-small SSOP package. The silicon-dioxide based capacitive isolation barrier supports an isolation withstand voltage of 3 kVRMS and an isolation working voltage of 566 VPK. Isolation breaks the ground loop between the communicating nodes and lets data transfer in the presence of large ground potential differences. The wide logic supply of the device (VCC1) supports interfacing with 1.8-V, 2.5-V, 3.3-V. and 5-V control logic. Functional Block Diagram shows the functional block diagram of the the half-duplex device.
