DESCRIPTION
•
•
•
Minimum Differential Output Voltage of 2.5 V
Into a 54-Ω Load
The SN65HVD05, SN75HVD05, SN65HVD06,
SN75HVD06, SN65HVD07, and SN75HVD07
combine
a 3-state differential line driver and
Open-Circuit, Short-Circuit, and Idle-Bus
Failsafe Receiver
1/8th Unit-Load Option Available (Up to 256
differential line receiver. They are designed for
balanced data transmission and interoperate with
ANSI
TIA/EIA-485-A
and
ISO
8482E
Nodes on the Bus)
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.

•
•
Bus-Pin ESD Protection Exceeds 16 kV HBM
Driver Output Slew Rate Control Options
Electrically Compatible With ANSI
TIA/EIA-485-A Standard
•
•
Low-Current Standby Mode . . . 1 µA Typical
Glitch-Free Power-Up and Power-Down
Protection for Hot-Plugging Applications
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.
