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.
