1 Features

• 1/8 Unit-load option available

(up to 256 nodes on the bus)

• Bus-pin ESD protection exceeds 15-kV HBM

• Glitch-free power-up and power-down protection

for hot-plugging applications

• 5-V Tolerant inputs

• Bus idle, open, and short-circuit failsafe

• Driver current limiting and thermal shutdown

• Designed for RS-422 and RS-485 networks

• 5-V Devices available, SN65HVD50-55

2 Applications

• Utility meters

• DTE and DCE interfaces

• Industrial, process, and building automation

• Point-of-sale (POS) pins and networks

3 Description

The SN65HVD3x devices are 3-state differential

line drivers and differential-input line receivers that

operate with 3.3-V power supply.

Each driver and receiver has separate input and

output pins for full-duplex bus communication

designs. They are designed for RS-422 and RS-485

data transmission over cable lengths of up to

1500 meters.

The SN65HVD30, SN65HVD31, and SN65HVD32

devices are fully enabled with no external enabling

pins.

The SN65HVD33, SN65HVD34, and SN65HVD35

devices have active-high driver enables and activelow

receiver enables. A low, less than 1 μA, standby

current can be achieved by disabling both the driver

and receiver.

All devices are characterized for ambient

temperatures from –40°C to 85°C. Low power

dissipation allows operation at temperatures up to

105°C or 125°C, depending on package option.
