Extended Temperatures.
(1) The signaling rate of a line is the number of voltage
transitions that are made per second expressed in the units
bits per second (bps).
(2) Custom temperature ranges available
2 Applications

3 Description
The SN65HVD11-HT device 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 VCC = 0.
