The RS485 is a +5V, half-duplex, ±15KV ESD protected RS485/RS422 transceiver circuit. The circuit contains single channel driver and single channel receiver internally.
The RS485 is a half-duplex type with drive enable (DE) and receive enable (RE) pins. When in the off state, the drive and receive outputs are high resistance.
The RS485 has a fail-safe circuit to ensure correct receiver output when the receiver input is open or shorted.
The RS485 receiver input impedance is 1/8 unit load, allowing up to 256 transceivers to be hooked up to the bus.
