HIGH OUTPUT FULL-DUPLEX RS-485 DRIVERS AND RECEIVERS
FEATURES
1/8 Unit-Load Option Available (Up to 256
Nodes on the Bus)
Bus-Pin ESD Protection Exceeds 15 kV HBM
Optional Driver Output Transition Times for
Signaling Rates
(1)
of 1 Mbps, 5 Mbps and 25
Mbps
Low-Current Standby Mode < 1
µA
Glitch-Free Power-Up and Power-Down Bus
I/Os
Bus Idle, Open, and Short Circuit Failsafe
Meets or exceeds the requirements of ANSI
TIA/EIA-485-A and RS-422 Compatible
3.3-V Devices available, SN65HVD30-39
The SN65HVD50, SN65HVD51, SN65HVD52,
SN65HVD56 and SN65HVD57 are fully enabled with
no external enabling pins. The SN65HVD56 and
SN65HVD57
implement
receiver
equalization
technology for improved performance in long distance
applications.
The SN65HVD53, SN65HVD54, SN65HVD55,
SN65HVD58, and SN65HVD59 have active-high
driver enables and active-low receiver enables. A
very low, less than 1 uA, standby current can be
achieved by disabling both the driver and receiver.
The SN65HVD58 and SN65HVD59 implement
receiver equalization technology for improved
performance in long distance applications.
All devices are characterized for operation from -40°
C to +85°.

DESCRIPTION
The SN65HVD5X devices are 3-state differential line
drivers and differential-input line receivers that
operate with a 5-V power supply. Each driver and
receiver has separate input and output pins for
full-duplex bus communication designs. They are
designed for balanced transmission lines and
interoperation
with
ANSI
TIA/EIA-485A,
TIA/EIA-422-B, ITU-T v.11 and ISO 8482:1993
standard-compliant devices.

The SN65HVD56 and SN65HVD58 implement
receiver equalization technology for improved jitter
performance on differential bus applications with data
rates up to 20 Mbps at cable lengths up to 160
meters.
The SN65HVD57 and SN65HVD59 implement
receiver equalization technology for improved jitter
performance on differential bus applications with data
rates in the range of 1 to 5 Mbps at cable lengths up
to 1000 meters.
(1)
The signaling rate of a line is the number of voltage
transitions that are made per second expressed in the units
bps (bits per second).
