DESCRIPTION/ORDERING INFORMATION  
SN75176 Footprint  
The SN65HVD11 combines a 3-state differential line  
driver and differential input line receiver that operates  
with a single 3.3-V power supply. It is designed for  
balanced transmission lines and meets or exceeds  
ANSI TIA/EIA-485-A and ISO 8482:1993, with the  
exception that the thermal shutdown is removed. This  
differential bus transceiver is a monolithic integrated  
circuit designed for bidirectional data communication  
on multipoint bus-transmission lines. The driver and  
receiver have active-high and active-low enables,  
respectively, that can be externally connected  
together to function as direction control.  
APPLICATIONS  
Down-Hole Drilling  
High Temperature Environments  
Digital Motor Controls  
Utility Meters  
Chassis-to-Chassis Interconnects  
Electronic Security Stations  
Industrial Process Control  
Building Automation  
The driver differential outputs and receiver differential  
inputs connect 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 VCC = 0.
