MAX14942GWE+

MAX14942GWE+ is an isolated RS-485/PROFIBUS-DP transceiver that provides 5000VRMS (60s) of galvanic isolation between the cable-side (RS-485 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 allows for robust communication up to 20Mbps. An integrated LDO provides a simple and space-efficient architecture for providing power to the cable side of the IC. This device includes one half-duplex driver/receiver channel. The receiver is 1/4-unit load, allowing up to 128 transceivers on a common bus. 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.
