Maxim Integrated (MAX14858GWE+) Transceiver RS422, RS485

Product Overview
The MAX14858GWE+ is a 5KVRMS isolated 25Mbps full duplex RS485/RS422 transceiver in 16 pin WSOIC package with ±35KV ESD protection. The MAX14856GWE+ isolated RS-485/RS-422 transceiver provides 5000VRMS (60s) of galvanic isolation between the cable-side (RS485/RS422 driver/receiver side) and the UART side of the device. The isolation improves communication by breaking ground loops and reduces noise when there are large differences in ground potential between ports. The device includes 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 cable-side or UART-side power supplies are below functional levels. It is used in industrial automation equipment, programmable logic controllers and power meters.
