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.
