Description

RS422/RS485 TXRX 500KBPS 5.5V WSOIC16
The MAX14948 isolated RS-485/RS-422 transceiver provides 5000VRMS (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 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. The driver outputs/receiver inputs are protected from ±30kV electrostatic discharge (ESD) to GNDB on the cable side, as specified by the Human Body Model (HBM). The MAX14948 is available in a wide body 16-pin SO package and operates over the -40°C to +85°C temperature range.
