The LTC®487 is a low power differential bus/line driver designed for multipoint data transmission standard RS485 applications with extended common mode range –7V to +12V. 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 mode range. Excessive power dissipation caused 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) and over the 4.75V to 5.25V supply voltage range.
