BELLING BL3085E
The BL3085E features reduced slew-rate driver that minimizes EMI and reduces reflections caused by improperly terminated cables, allowing error-free data transmission up to 500kbps. The transceiver typically draws 500 micron ampere of supply current when unloaded, or when fully loaded with the driver disabled. The BL3085E is intended for half-duplex communications.GENERAL DESCRIPTION
TheBL3085E is a +/- 15kV electrostatic discharge (ESD) protected, high-speed transceiver for RS-485 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 logic-high even if all transmitters on a terminated bus are disabled. All transmitter outputs and receiver inputs are protected to +/- 15kV using the Human Body Model. All devices have a 1/8-unit-load receiver input impedance that allows up to 256 transceivers on the bus.APPLICATIONS
