DESCRIPTION
The SN65HVD10, SN75HVD10, SN65HVD11,
SN75HVD11, SN65HVD12, and SN75HVD12
combine a 3-state differential line driver and
differential input line receiver that operate with a
single 3.3-V power supply. They are designed for
balanced transmission lines and meet or exceed
ANSI standard TIA/EIA-485-A and ISO 8482:1993.
These differential bus transceivers are monolithic
integrated circuits designed for bidirectional data
communication on multipoint bus-transmission lines.
The drivers and receivers have active-high and
active-low enables respectively, that can be
externally connected together to function as direction
control. Very low device standby supply current can
be achieved by disabling the driver and the receiver.
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
whenever the driver is disabled or V_CC = 0. These
parts feature wide positive and negative
common-mode voltage ranges, making them suitable
for party-line applications.
