Description

The LTC487® 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 LTC487 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 of LTC487 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.
