MAX14858GWE+

MAX14858GWE+ is an isolated RS-485/RS-422 transceiver that 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. This device includes one drive channel and one receive channel. The receiver is a 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. It is approved by UL according to UL1577, cUL according to CSA bulletin 5A, VDE 0884-10. It is used in applications such as industrial automation equipment, programmable logic controllers, HVAC, and power meters.
