DESCRIPTION/ORDERING INFORMATION

The SN65HVD10, SN65HVD11, and SN65HVD12

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.

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.
