Quad Low Power

RS485 Driver

DESCRIPTIO

EATURE

Very Low Power: I_CC= 110µA Typ

Designed for RS485 or RS422 Applications

Single 5V Supply

The LTC487^®is a low power differential bus/line driver

designedformultipointdatatransmissionstandardRS485

applications with extended common-mode range (–7V to

12V). It also meets RS422 requirements.

■

The driver features three-state outputs, with the driver

outputs maintaining high impedance over the entire com-

mon-mode range. Excessive power dissipation caused by

bus contention or faults is prevented by a thermal shut-

down circuit which forces the driver outputs into a high

impedance state.

O U

Both AC and DC specifications are guaranteed from 0°C to

70°C (Commercial), –40°C to 85°C (Industrial) and over

the 4.75V to 5.25V supply voltage range.
