DESCRIPTION
   The A3085A is a half-duplex RS-485 transceiver with ±15kV IEC 61000-4-2 contact ESD protection. This device contains one driver and one receiver. The A3085A includes fail-safe circuitry, which guarantees a logic-high receiver output when the receiver inputs are open or shorted. This means that the receiver output will be logic high even if all transmitters on a terminated bus are disabled. The A3085A features reduced slew-rate driver that minimizes EMI and reduces reflections caused by improperly terminated cables, allowing error-free data transmission up to 500kbps. The A3085A has a 1/8 unit load receiver input impedance that allows up to 256 transceivers on the bus.
   The A3085A is available in SOP8 package
