DESCRIPTION
The SN65HVD3x devices are 3-state differential line
drivers and differential-input line receivers that
operate with 3.3-V power supply.

Enhanced Product-Change Notification
Qualification Pedigree(1)
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.
Available in the Texas Instruments
NanoStar™ and NanoFree™ Packages
•
1/8 Unit-Load Option Available (up to 256
Nodes on the Bus)
The SN65HVD30, SN65HVD31, SN65HVD32,
SN65HVD36, and SN65HVD37 are fully enabled
with no external enabling pins. The SN65HVD36 and

•
Low-Current Standby Mode: <1 µA
Glitch-Free Power-Up and Power-Down
Protection for Hot-Plugging Applications
The SN65HVD33, SN65HVD34, SN65HVD35,
SN65HVD38, and SN65HVD39 have active-high
driver enables and active-low receiver enables. A low
(less than 1 µA) standby current can be achieved by
disabling both the driver and receiver. The
SN65HVD38 and SN65HVD39 implement receiver
equalization technology for improved performance in
long distance applications.

The SN65HVD36 and SN65HVD38 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.
(1)
Component qualification in accordance with JEDEC and
industry standards to ensure reliable operation over an
extended temperature range. This includes, but is not limited
to, Highly Accelerated Stress Test (HAST) or biased 85/85,
temperature cycle, autoclave or unbiased HAST,
electromigration, bond intermetallic life, and mold compound
life. Such qualification testing should not be viewed as
justifying use of this component beyond specified
performance and environmental limits.
The SN65HVD37 and SN65HVD39 implement
receiver equalization technology for improved jitter
performance on differential bus applications with
data rates in the range of 1 Mbps to 5 Mbps at cable
lengths up to 1000 meters.
(2)
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).
All devices are characterized for operation from
–55°C to 125°C.
