LTC1484

Low Power

RS485 Transceiver

with Receiver Fail-Safe

DESCRIPTIO

FEATURES

The LTC^®1484 is a low power RS485 compatible trans-

ceiver. Inreceivermode, itoffersafail-safefeaturewhich

Drives Low Cost Residential Telephone Wires

Low Power: I_CC= 700µA Max with Driver Disabled

I_CC= 900µA Max for Driver Enable with No Load

20µA Max Quiescent Current in Shutdown Mode

Single 5V Supply

–7V to 12V Common Mode Range Permits ±7V

Ground Difference Between Devices on the Data Line

Power Up/Down Glitch-Free Driver Outputs

Up to 32 Transceivers on the Bus

signal present. No external components are required to

ensure the high receiver output state.

■

Both driver and receiver feature three-state outputs with

separate receiver and driver control pins. The driver

outputs maintain high impedance over the entire com-

mon mode range when three-stated. Excessive power

dissipation caused by bus contention or faults is pre-

vented by a thermal shutdown circuit that forces the

driver outputs into a high impedance state.

■

Enhanced ESD protection allows the LTC1484 to with-

stand ±15kV (human body model), IEC-1000-4-2 level 4

(±8kV) contact and level 3 (±8kV) air discharge ESD

without latchup or damage.

Pin Compatible with the LTC485

Available in 8-Lead MSOP, PDIP and SO Packages

The LTC1484 is fully specified over the commercial and

industrial temperature ranges and is available in 8-lead

MSOP, PDIP and SO packages.
