MAX14945EWE+ Description
The MAX14945EWE+ isolated RS 485/RS 422 transceiver provides 2750VRMS (the 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. The MAX14945EWE+ allows for robust communication at any speed up to 500kbps. The device includes one half-duplex drive/receive channel. The receiver is a 1/8-unit load, allowing up to 256 transceivers on a common bus.
MAX14945EWE+ Features
Integrated LDO for Cable-Side Power
Compliant with RS-485 EIA/TIA-485 Standard
500kbps Maximum Data Rate
Allows Up to 256 Devices on the Bus
±30kV ESD (HBM) on Driver Outputs/Receiver Inputs
2.75kVRMS Withstand-Isolation Voltage for 60s (VISO)
630VPEAK Maximum Repetitive Peak-Isolation Voltage (VIORM)
MAX14945EWE+ Applications
Industrial Automation Equipment
Programmable Logic Controllers
HVAC
Power Meters
