Maxim Integrated MAX14945
The MAX14945 isolated RS-485/RS-422 transceiver provides 2750VRMS (60s) of galvanic isolation between the cable side (RS-485/RS-422 driver/receiver side) and the UART side of the device. This device allows for robust communication at any speed up to 500kbps. The device includes one half-duplex drive/receive channel.| Part No. | MAX14945 |

GENERAL DESCRIPTION
Isolation improves communication by breaking ground loops and reduces noise when there are large differences in ground potential between ports. Signals are passed across the isolation barrier through integrated high-voltage capacitors. The receiver is 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 the cable side or UART side power supplies are below funct
