SN65076B Datasheet | Texas Instruments

description logic diagram (positive logic) The SN65076B and SN75076B differential bus transceivers are monolithic integrated circuits designed for bidirectional data munication on multipoint bus transmission lines. They are designed for noisy environments, where a low-impedance termination to ground is required. D3 2 RE 1 R 7 A 6 B BUS The SN65076B and SN75076B bine a differential line driver and a differential input line receiver, both of which operate from a single 5-V power supply. The receiver has an active-low enable. The driver differential outputs and the receiver differential inputs are connected internally to form differential input/output (I/O) bus ports that are designed to offer minimum loading to the bus whenever the driver is disabled or VCC = 0. These ports feature wide positive and negative mon-mode voltage ranges making the device suitable for party-line applications.
