MAX14945
EVALUATION KIT AVAILABLE
2.75kVRMS Isolated 500kbps Half-Duplex RS-485/ RS-422 Transceiver with ±30kV ESD Protection
General Description
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. 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. This device allows for robust communication at any speed up to 500kbps.
The device includes one half-duplex drive/receive channel. The receiver is 1/8-unit load, allowing up to 256 transceivers on a common bus.
