MAX13485EESA+T

The MAX13485E/MAX13486E +5V half- duplex, ±15kV ESD- protected RS- 485 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 MAX13485E/MAX13486E include a hot- swap capability to eliminate false transitions on the bus during power- up or live- insertion. The MAX13485E features reduced slew- rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, allowing error- free transmission up to 500kbps. The MAX13486E driver slew rate is not limited, allowing transmit speeds up to 16Mbps. The MAX13485E/MAX13486E feature a 1/4- unit load receiver input impedance, allowing up to 128 transceivers on the bus. These devices are intended for half- duplex communications. All driver outputs are protected to ±15kV ESD using the Human Body Model. The MAX13485E/MAX13486E are available in 8- pin SO and space- saving 8- pin uDFN packages. The devices operate over the extended - 40℃ to +85℃ temperature range.
