3.3V-Supply RS-485 with IEC ESD Protection

Check for Samples: SN65HVD72, SN65HVD75, SN65HVD78

FEATURES

APPLICATIONS

•

Small-size MSOP Packages Save Board Space,

or SOIC for Drop-in Compatibility

•

Factory Automation

Telecomm Infrastructure

Motion Control

•

Bus I/O Protection

–

> ±15kV HBM protection

DESCRIPTION

These devices have robust 3.3V drivers and receivers

> ±12kV IEC61000-4-2 Contact Discharge

> ±12kV IEC61000-4-2 Air-Gap Discharge

small package for demanding industrial

•

Extended Industrial Temperature Range

–40°C to 125°C

applications. The bus pins are robust to ESD events,

with high levels of protection to Human-Body Model

and IEC Contact Discharge specifications.

Large Receiver Hysteresis (80 mV) for Noise

Rejection

These devices each combine a differential driver and

a differential receiver, which operate from a single

3.3-V power supply. 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. These devices all

feature a wide common-mode voltage range making

the devices suitable for multi-point applications over

long cable runs. These devices are characterized

from -40°C to 125°C.

Low Unit-loading allows over 200 connected

nodes

Low Power Consumption

–

Low Standby Supply Current: < 2 µA

I_CC<1 mA Quiescent During Operation

•

5V-Tolerant Logic Inputs Compatible With

3.3 V or 5 V Controllers

Signaling Rate Options Optimized for:

250 kbps, 20 Mbps, 50 Mbps
