DESCRIPTIO

The LTC486 is a low power differential bus/line driver

designedformultipointdatatransmissionstandardRS485

applications with extended common-mode range (12V to

–7V). It also meets RS422 requirements.

TheCMOSdesignofferssignificantpowersavingsoverits

bipolarcounterpartwithoutsacrificingruggednessagainst

overload or ESD damage.

■

The driver features three-state outputs, with the driver

outputs maintaining high impedance over the entire

common-moderange.Excessivepowerdissipationcaused

by bus contention or faults is prevented by a thermal

shutdown circuit which forces the driver outputs into a

high impedance state.

28ns Typical Driver Propagation Delays

with 5ns Skew

Pin Compatible with the SN75172, DS96172,

µA96172, and DS96F172

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

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

4.75V to 5.25V supply voltage range.
