description  
The SN65076B and SN75076B differential bus  
transceivers are monolithic integrated circuits  
designed for bidirectional data communication on  
multipoint bus transmission lines. They are  
designed for noisy environments, where a  
low-impedance termination to ground is required.

The SN65076B and SN75076B combine 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  
V
= 0. These ports feature wide positive and negative common-mode voltage ranges making the device  
CC  
suitable for party-line applications.
