Description

General part information

ISOW1412 Series

The ISOW14x2 devices are galvanically-isolated RS-485/RS-422 transceiver s with a built-in isolated DC-DC converter, that eliminates the need for a separate isolated power supply in space constrained isolated designs. The low-emissions, isolated DC-DC converter meets CISPR 32 radiated emissions Class B standard with just two ferrite beads on a simple two-layer PCB. Additional 20 mA output current can be used to power other circuits on the board. An integrated 2 Mbps GPIO channel helps remove any additional digital isolator or optocoupler for diagnotstics, LED indication or supply monitoring.
