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 or 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

(C- and I-ꢀrades)

70mV Typical Input Hysteresis

30ns Typical Driver Propagation Delays

The receiver has a fail-safe feature which guarantees a

high output state when the inputs are left open.

with 5ns Skew for Up to 2.5MB Operation

Pin Compatible with ±±0V Protected LTC28±2

The LTC485 is fully specified over the commercial and

extended industrial temperature range.
