Quad Low Power  
RS485 Driver  
FEATURES  
DESCRIPTION  
The LTC®486 is a low power differential bus/line driver  
designedformultipointdatatransmissionstandardRS485  
applications with extended common-mode range (12V to  
–7V). It also meets RS422 requirements.

–7V to 12V Bus Common-Mode Range Permits 7V  
GND Difference Between Devices on the Bus  
The CMOS design offers significant power savings over  
its bipolar counterpart without sacrificing ruggedness  
against overload or ESD damage.  
n
Thermal Shutdown Protection  
n
Power-Up/Down Glitch-Free Driver Outputs Permit  
Live Insertion/Removal of Package  
n
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.  
Driver Maintains High Impedance in Three-State or  
with the Power Off

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.
