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.

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.
