MAX14948EWE+, RS-485 Interface IC 5kVRMS Isolated 500kbps Half-Duplex RS-485/RS-422 Transceiver with 30kV ESD Protection
Semiconductors\Interface ICs\RS-485 Interface ICMAX14948 RS-485/RS-422 Transceiver
Analog Devices MAX14948 RS-485/RS-422 Transceiver provides 5000V RMS (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 allows for robust communication up to 500kbps. The MAX14948 includes one half-duplex drive/receive channel. The receiver is a 1/8-unit load, allowing up to 256 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.
