DS7837 Datasheet (National Semiconductor)

DS7837, Hex Unified Bus Receiver

The DS7837 DS8837 are high speed receivers designed for use in bus organized data transmission systems interconnected by terminated 120X impedance lines The external termination is intended to be 180X resistor from the bus to the a 5V logic supply together with a 390X resistor from the bus to ground
