The DS3885 is one in a series of transceivers designed specifically for the implementation of high performance Futurebus a and proprietary bus interfaces The DS3885 Arbitration Transceiver is designed to conform to IEEE 1194 1 (Backplane Transceiver Logic BTL) as specified in the IEEE 896 2 Futurebus a specification The Arbitration Transceiver incorporates the competition logic internally which simplifies the implementation of a Futurebus a application by minimizing the on board logic required The DS3885 driver output configuration is an NPN open collector which allows Wired-OR connection on the bus Each driver output incorporates a Schottky diode in series with its collector to isolate the transistor output capacitance from the bus thus reducing the bus loading in the inactive state The BTL drivers also have high sink current capability to comply with the bus loading requirements defined within IEEE 1194 1 BTL specification
