SN65HVD178x-Q1 Fault-Protected RS-485 Transceivers With 3.3-V to 5-V Operation

1 Features

3 Description

These devices are designed to survive overvoltage

faults such as direct shorts to power supplies, mis-

wiring faults, connector failures, cable crushes, and

tool mis-applications. They are also robust to ESD

events, with high levels of protection to the human-

body-model specification.

•

Qualified for Automotive Applications

•

AEC-Q100 Qualified With the Following Results

–

Device Temperature Grade 1:

–40°C to 125°C Ambient Operating

Temperature Range

–

Device HBM ESD Classification Level H2

Device CDM ESG Classification Level C3B

These devices combine a differential driver and a

differential receiver, which operate from a single

power supply. In the 'HVD1782, the driver differential

outputs and the receiver differential inputs are

connected internally to form a bus port suitable for

half-duplex (two-wire bus) communication. This port

features a wide common-mode voltage range, making

the devices suitable for multipoint applications over

long cable runs. These devices are characterized

from –40°C to 125°C. These devices are pin-

compatible with the industry-standard SN75176

transceiver, making them drop-in upgrades in most

systems.

•

Bus-Pin Fault Protection to:

–

> ±70 V ('HVD1780-Q1, 'HVD1781-Q1)

> ±30 V ('HVD1782-Q1)

•

Operation With 3.3-V to 5-V Supply Range

±16-kV HBM Protection on Bus Pins

Reduced Unit Load for up to 320 Nodes

Failsafe Receiver for Open-Circuit, Short-Circuit

and Idle-Bus Conditions

•

Low Power Consumption

These devices are fully compliant with ANSI TIA/EIA

485-A with a 5-V supply and can operate with a 3.3-V

supply with reduced driver output voltage for low-

power applications. For applications where operation

is required over an extended common-mode voltage

range, see the SN65HVD1785 (SLLS872) data sheet.
