Product Description
The UM13087S8 is ±8kV electrostatic discharge (ESD)-protected, high-speed transceivers for RS-422 communication that contain one driver and one receiver. The device features 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 a logic high if all transmitters on a terminated bus are disabled (high impedance). The UM13087S8 allows transmit speeds up to 10Mbps. The device features enhanced ESD protection. All transmitter outputs and receiver inputs are protected to ±8kV using the Human Body Model.
The device has a 1/8-unit-load receiver input impedance that allows up to 256 transceivers on the bus. The UM13087S8 is intended for full-duplex communications.
