485-CN485(N)

CN485/CN485N is a +5V, half-duplex, ±15KV ESD protected RS485/RS-422 transceiver circuit. The circuit contains one driver and one receiver. CN485/CN485N is half-duplex and has drive enable (DE) and receive enable (____RE) pins. When in the off state, the drive and receive outputs are in high impedance state. CN485/CN485N has a fail-safe circuit to ensure that the receiver output is correct when the receiver input is open or shorted. The CN485/CN485N receiver input impedance is 1/8 unit load, allowing up to 256 transceivers to be connected to the bus.
