MAX13080EMAX13084E/ MAX13086EMAX13089E +5.0V, 15kV ESD-Protected, Fail-Safe, Hot-Swap, RS-485/RS-422 Transceivers General Description Features The MAX13080EMAX13089E +5.0V, 15kV ESD-protect- +5.0V Operation ed, RS-485/RS-422 transceivers feature one driver and Extended ESD Protection for RS-485/RS-422 I/O Pins one receiver. These devices include fail-safe circuitry, 15kV Human Body Model guaranteeing a logic-high receiver output when receiver inputs are open or shorted. The receiver outputs a logic- True Fail-Safe Receiver While Maintaining high if all transmitters on a terminated bus are disabled EIA/TIA-485 Compatibility (high impedance). The MAX13080E family include a hot- Hot-Swap Input Structures on DE and RE swap capability to eliminate false transitions on the bus during power-up or hot insertion. Enhanced Slew-Rate Limiting Facilitates Error- The MAX13080E/MAX13081E/MAX13082E feature Free Data Transmission reduced slew-rate drivers that minimize EMI and (MAX13080EMAX13084E/MAX13089E) reduce reflections caused by improperly terminated Low-Current Shutdown Mode (Except cables, allowing error-free data transmission up to MAX13081E/MAX13084E/MAX13087E) 250kbps. The MAX13083E/MAX13084E also feature slew-rate-limited drivers but allow transmit speeds up to Pin-Selectable Full-/Half-Duplex Operation 500kbps. The MAX13086E/MAX13087E/ MAX13088E (MAX13089E) driver slew rates are not limited, making transmit Phase Controls to Correct for Twisted-Pair speeds up to 16Mbps possible. The MAX13089E slew Reversal (MAX13089E) rate is pin selectable for 250kbps, 500kbps, and 16Mbps.
