DESCRIPTION

The

SN65HVD05,

SN75HVD05,

SN65HVD06,

SN75HVD06, SN65HVD07, and SN75HVD07 combine

a 3-state differential line driver and differential line

receiver. They are designed for balanced data

transmission

and

interoperate

with

ANSI

TIA/EIA-485-A and ISO 8482E standard-compliant

devices. The driver is designed to provide a differential

output voltage greater than that required by these

standards for increased noise margin. The drivers and

receivers have active-high and active-low enables

respectively, which 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 whenever the driver is disabled or not

powered. These devices feature wide positive and

negative common-mode voltage ranges, making them

suitable for party-line applications.
