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 VCC = 0. These parts feature wide positive
and negative common-mode voltage ranges, making
them suitable for party-line applications.
