DESCRIPTION/ORDERING INFORMATION
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.
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 V
