The MAX14856/MAX14858 isolated RS-485/RS-422 transceivers provide 5000VRMS (60s) of galvanic isolation between the cable side (RS-485/RS-422 driver/ receiver-side) and the UART side of the device. Isolation improves communication by breaking ground loops and reduces noise when there are large differences in ground potential between ports. These devices allow for robust communication up to 500kbps (MAX14856) or 25Mbps (MAX14858). The devices include one drive channel and one receive channel. The receiver is 1/4-unit load, allowing up to 128 transceivers on a common bus. Integrated true fail-safe circuitry ensures a logic-high on the receiver output when inputs are shorted or open. Undervoltage lockout disables the driver when the cable side or UART side power supplies are below functional levels. The driver outputs and receiver inputs are protected from ±35kV electrostatic discharge (ESD) to GNDB on the cable side, as specified by the Human Body Model (HBM). The devices are available in a wide-body 16-pin SOIC package and operate over the -40°C to +105°C temperature range.
