description  
The SN65ALS176 and SN75ALS176 series differential bus transceivers are designed for bidirectional data  
communication on multipoint bus transmission lines. They are designed for balanced transmission lines and  
meet TIA/EIA-422-B, TIA/EIA-485-A, and ITU Recommendations V.11 and X.27.  
The SN65ALS176 and SN75ALS176 series combine a 3-state, differential line driver and a differential input line  
receiver, both of which operate from a single 5-V power supply. The driver and receiver have active-high and  
active-low enables, respectively, that can be connected together externally to function as a direction control.  
The driver differential outputs and the receiver differential inputs are connected internally to form a differential  
input/output (I/O) bus port that is designed to offer minimum loading to the bus when the driver is disabled or  
V
= 0. This port features wide positive and negative common-mode voltage ranges, making the device  
CC  
suitable for party-line applications.  
The SN65ALS176 is characterized for operation from 40°C to 85°C, and the SN75ALS176 series is  
characterized for operation from 0°C to 70°C.
