DESCRIPTION
The
SN75HVD06, SN65HVD07, and SN75HVD07 combine
a 3-state differential line driver and differential line
receiver. They are designed for balanced data
transmission
and
interoperate
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.
SN65HVD05,
SN75HVD05,
SN65HVD06,
with
ANSI
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.
