MAX3077EASA+ Product Details

General Description

  The MAX3070E–MAX3079E 3.3V, ±15kV ESD-protected, RS-485/RS-422 transceivers feature one driver and one receiver. These devices include fail-safe circuitry, guaranteeing a logic-high receiver output when receiver inputs are open or shorted. The receiver outputs a logic-high if all transmitters on a terminated bus are disabled (high impedance). The devices include a hot-swap capability to eliminate false transitions on the bus during power-up or hot insertion.

  The MAX3070E/MAX3071E/MAX3072E feature reduced slew-rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, allowing errorfree data transmission up to 250kbps. The MAX3073E/ MAX3074E/MAX3075E also feature slew-rate-limited drivers but allow transmit speeds up to 500kbps. The MAX3076E/MAX3077E/MAX3078E driver slew rates are not limited, making transmit speeds up to 16Mbps possible. The MAX3079E slew rate is pin-selectable for 250kbps, 500kbps, and 16Mbps.

  The MAX3072E/MAX3075E/MAX3078E are intended for half-duplex communications, and the MAX3070E/ MAX3071E/MAX3073E/MAX3074E/MAX3076E/ MAX3077EASA+ are intended for full-duplex communications. The MAX3079E is selectable for half-duplex or full-duplex operation. It also features independently programmable receiver and transmitter output phase through separate pins.

  The MAX3070E–MAX3079E transceivers draw 800μA of supply current when unloaded, or when fully loaded with the drivers disabled. All devices have a 1/8-unit load receiver input impedance, allowing up to 256 transceivers on the bus
