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.
