The XL13085/XD13085 +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 XL13085/XD13085 includes a hot-swap capability to eliminate false transitions on the bus during power-up or hot insertion.
The XL13085/XD13085 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 XL13085/XD13085 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 XL13085/XD13085 has a 1/8-unit load receiver input impedance, allowing up to 256 transceivers on the bus.
