FEATURES

DESCRIPTION

Common-Mode Voltage Range (−20 V to 25 V)

More Than Doubles TIA/EIA-485 Requirement

The transceivers in the HVD2x family offer performance

far exceeding typical RS−485 devices. In addition to

meeting all requirements of the TIA/EIA−485−A standard,

the HVD2x family operates over an extended range of

common-mode voltage, and has features such as high

ESD protection, wide receiver hysteresis, and failsafe

operation. This family of devices is ideally suited for

long-cable networks, and other applications where the

environment is too harsh for ordinary transceivers.

Receiver Equalization Extends Cable Length,

Signaling Rate (HVD23, HVD24)

Reduced Unit-Load for up to 256 Nodes

Bus I/O Protection to Over 16-kV HBM

Failsafe Receiver for Open-Circuit,

Short-Circuit and Idle-Bus Conditions

Low Standby Supply Current 1-µA Max

These devices are designed for bidirectional data

transmission on multipoint twisted-pair cables. Example

applications are digital motor controllers, remote sensors

and terminals, industrial process control, security stations,

and environmental control systems.

More Than 100 mV Receiver Hysteresis

APPLICATIONS

Long Cable Solutions

−

Factory Automation

Security Networks

Building HVAC

These devices combine a 3-state differential driver and a

differential receiver, which operate from a single 5-V power

supply. The driver differential outputs and the receiver

differential inputs are connected internally to form a

differential bus port that offers minimum loading to the bus.

This port features an extended common-mode voltage

range making the device suitable for multipoint

applications over long cable runs.
