MAX13085EESA+T

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.
