Maxim Integrated
General Description
The MAX13448E full-duplex RS-485 transceiver features inputs and outputs fault protected up to ±80V (with respect to ground). The device operates from a +3.0V to +5.5V supply and features true fail-safe circuitry, guaranteeing a logic-high receiver output when the receiver inputs are open or shorted. This enables all receiver outputs on a terminated bus to output logic-high when all transmitters are disabled.
FEATUREs
♦ ±80V Fault Protection on the RS-485 I/O Ports
