Product Details

The MAX13085E +5.0V, ±15kV ESD-protected, RS-485/RS-422 transceiver features one driver and one receiver. The device includes 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 MAX13085E includes a hot-swap capability to eliminate false transitions on the bus during power-up or hot insertion.
The MAX13085E features reduced slew-rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, allowing error-free data transmission up to 500kbps.
The MAX13085E is ideal for half-duplex communications and it draws 1.2mA of supply current when unloaded or when fully loaded with the drivers disabled. The MAX13085E has a 1/8-unit load receiver input impedance, allowing up to 256 transceivers on the bus.
The MAX13085E is available in an 8-pin SO and PDIP packages.
