LT1785/LT1785A/

LT1791/LT1791A

60V Fault Protected

RS485/RS422 Transceivers

FEATURES

DESCRIPTION

TheLT^®1785/LT1791arehalf-duplexandfull-duplexdiffer-

ential bus transceivers for RS485 and RS422 applications

which feature on-chip protection from overvoltage faults

on the data transmission lines. Receiver input and driver

output pins can withstand voltage faults up to ±±60 with

respect to ground with no damage to the device. Faults

may occur while the transceiver is active, shut down or

powered off.

Protected from Overvoltage Line Faults to ±±0ꢀ

Pin Compatible with LTC485 and LTC491

High Input Impedance Supports Up to 128 Nodes

No Damage or Latchup to ESD

IEC-1666-4-2 Level 4: ±15k0 Air Discharge

IEC-1666-4-2 Level 2: ±4k0 Contact Discharge

Controlled Slew Rates for EMI Emissions Control

Guaranteed High Receiver Output State for Floating,

Shorted or Inactive Inputs

Data rates to 256kbaud on networks of up to 128 nodes

are supported. Controlled slew rates on the driver out-

putscontrol EMI emissions and improve data transmis-

sion integrity on improperly terminated lines. Drivers are

speciﬁed to operate with inexpensive cables as low as

72Ω characteristic impedance.

Outputs Assume a High Impedance When Off or

Powered Down

Drives Low Cost, Low Impedance Cables

Short-Circuit Protection on All Outputs

Thermal Shutdown Protection

Guaranteed Operation to 125°C

The LT1785A/LT1791A devices have “fail-safe” receiver

inputstoguaranteeareceiveroutputhighforshorted,open

or inactive data lines. On-chip ESD protection eliminates

need for external protection devices.

APPLICATIONS

Industrial Control Data Networks

CAN Bus Applications

The LT1785/LT1785A are available in 8-lead DIP and SO

packages and the LT1791/LT1791A in 14-lead DIP and

SO packages.
