TYPICAL APPLICATION
DESCRIPTION
Quad Low Power
RS485 Driver
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.
The CMOS design offers significant power savings over
its bipolar counterpart without sacrificing ruggedness
against 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.
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.
