The XD/XL485 is a +5V, half-duplex, ±15KV ESD protected high speed RS485 transceivers circuit. The circuit contains one driver and one receiver. A transmission rate of 10Mbps can be realized.
The XD/XL485 is a half-duplex type with drive enable (DE) and receive enable (RE) pins, and the drive and receive outputs are high-resistance when off.
The XD/XL485 has a fail-safe circuit to ensure correct receiver output when the receiver input is open or shorted.
The XD/XL485 receiver input impedance is 1/8 unit load, allowing up to 256 transceivers to be hooked up to the bus.
