Product Details

The LTC®1485 is a low power differential bus/line trans-ceiver designed for multipoint data transmission standardRS485 applications with extended common-mode range(12V to – 7V). It also meets the requirements of RS422.

​The CMOS with Schottky design offers significant powersavings  over  its  bipolar  counterpart  without  sacrificingruggedness against overload or ESD damage.

The driver and receiver feature three-state outputs, withthe driver outputs maintaining high impedance over theentire common-mode range. Excessive power dissipationcaused  by  bus  contention  or  faults  is  prevented  by  athermal shutdown circuit which forces the driver outputsinto a high impedance state. I/O pins are protected againstmultiple ESD strikes of over ±10kV.

The  receiver  has  a  fail-safe  feature  which  guarantees  ahigh output state when the inputs are left open.

Both AC and DC specifications are guaranteed from – 40°Cto 85°C and 4.75V to 5.25V supply voltage range.
