LTC485

Low Power RS485

Interface Transceiver

FeaTures

DescripTion

The LTC^®485 is a low power differential bus/line trans-

ceiverdesignedformultipointdatatransmissionstandard

RS485 applications with extended common mode range

(12V to –7V). It also meets the requirements of RS422.

Low Power: I = 300μA Typ

Designed for RS485 Interface Applications

Single 5V supply

–7V to 12V Bus Common Mode Range Permits

±7V ꢀround Difference Between Devices on the Bus

The CMOS design offers significant power savings over

its bipolar counterpart without sacrificing ruggedness

against overload of ESD damage.

Thermal Shutdown Protection

Power-Up/Down ꢀlitch-Free Driver Outputs

Permit Live Insertion or Removal of Transceiver

The driver and receiver feature three-state outputs, with

the driver outputs maintaining high impedance over the

entire common mode range. Excessive power dissipa-

tion caused 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

Combined Impedance of a Driver Output and

Receiver Allows Up to 32 Transceivers on the Bus

70mV Typical Input Hysteresis

30ns Typical Driver Propagation Delays

with 5ns Skew for Up to 2.5MB Operation

The receiver has a fail-safe feature which guarantees a

high output state when the inputs are left open.

Pin Compatible with ±±0V Protected LT1785 and

52Mbps LTC1±85

The LTC485 is fully specified over the commercial and

extended industrial temperature range.
