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
♦ True Fail-Safe Receiver
♦ Hot-Swap Input Structure on DE
♦ ESD Protection on the RS-485 I/O Ports ±8kV Human Body Model
♦ Slew-Rate Limiting Facilitates Error-Free Data Transmission
♦ 1/8-Unit Load Allows Up to 256 Transceivers on the Bus
♦ -7V to +12V Common-Mode Input Voltage Range
♦ +3.0V to +5.5V Operating Supply Voltage
♦ Available in 14-Pin SO Package
