Texas Instruments ISOW14x2 Isolated RS-485/RS-422 Transceiver comes with a built-in isolated DC-DC converter, eliminating 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 two ferrite beads on a simple two-layer PCB. The additional 20mA output current can power other circuits on the board. The Texas Instruments ISOW14x2 has an integrated 2Mbps GPIO channel that helps remove any additional digital isolator or optocoupler for diagnostics, LED indication, or supply monitoring.
