LTC485

Low Power RS485

Interface Transceiver

FEATURES

DESCRIPTIO

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_CC= 300µA Typ

■

Designed for RS485 Interface Applications

■

Single 5V supply

–7V to 12V Bus Common Mode Range Permits

■

±7V Ground Difference Between Devices on the Bus

■

Thermal Shutdown Protection

■

Power-Up/Down Glitch-Free Driver Outputs

Permit Live Insertion or Removal of Transceiver

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

Pin Compatible with ±60V Protected LT1785 and

52Mbps LTC1685

■

The driver and receiver feature 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.

■

The receiver has a fail-safe feature which guarantees a

high output state when the inputs are left open.

■

The LTC485 is fully specified over the commercial and

extended industrial temperature range.
