The MAX3070E–MAX3079E 3.3V, ±15kV ESD-protected,RS-485/RS-422 transceivers feature one driver and onereceiver. These devices include fail-safe circuitry, guaranteeinga logic-high receiver output when receiverinputs are open or shorted. The receiver outputs a logichigh if all transmitters on a terminated bus are disabled(high impedance). The MAX3070E–MAX3079E include ahot-swap capability to eliminate false transiTIons on thebus during power-up or hot inserTIon.The MAX3070E/MAX3071E/MAX3072E feature reducedslew-rate drivers that minimize EMI and reduce reflecTIonscaused by improperly terminated cables, allowingerror-free data transmission up to 250kbps. TheMAX3073E/MAX3074E/MAX3075E also feature slewrate-limited drivers but allow transmit speeds up to500kbps. The MAX3076E/MAX3077E/MAX3078E driverslew rates are not limited, making transmit speeds up to16Mbps possible. The MAX3079E slew rate is pinselectable for 250kbps, 500kbps, and 16Mbps.
