The XD/ XL3085 is a +5V, half-duplex, ±15KV ESD protected RS485/RS-422 transceiver circuit. The circuit contains one driver and one receiver.
The XD/XL3085 is a half-duplex type with drive enable (DE) and receive enable E()R pins, and the drive and receive outputs are high-impedance when in the off state.
The XD/XL3085 has a failsafe circuit to ensure that the receiver output is correct when the receiver input is open or shorted.
The XD/XL3085 receiver input impedance is 1/8 unit load, allowing up to 256 transceivers to be hooked up to the bus.
