MAX14938GWE+, RS-485 Interface IC 2.75kVRMS Isolated 20Mbps Half-Duplex PROFIBUS/RS-485 Transceivers with 35kV ESD Protection
Semiconductors\Interface ICs\RS-485 Interface ICMAX14938/MAX14939 RS-485/PROFIBUS-DP Transceivers
Analog Devices MAX14938/MAX14939 Isolated RS-485/PROFIBUS-DP Transceivers provide 2750VRMS (60s) of galvanic isolation between the RS-485 driver/receiver side and the UART side of the device. Isolation improves communication by breaking ground loops. It also reduces noise when large differences in ground potential between ports exist. These devices allow for robust communication up to 20Mbps. An integrated LDO provides a simple and space-efficient architecture for powering the cable side of the IC. Each device includes one half-duplex driver/receiver 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 cable-side or UART-side power supplies are below functional levels.
