DS36C278 Low Power Multipoint EIA-RS-485 Transceiver

Check for Samples: DS36C278

FEATURES

DESCRIPTION

The DS36C278 is a low power differential bus/line

transceiver designed to meet the requirements of RS-

485 standard for multipoint data transmission. In

addition it is compatible with TIA/EIA-422-B.

•

100% RS-485 Compliant

Guaranteed RS-485 Device Interoperation

–

•

Low Power CMOS Design: I_CC500 μA Max

Built-In Power Up/Down Glitch-Free Circuitry

The CMOS design offers significant power savings

over its bipolar and ALS counterparts without

sacrificing ruggedness against ESD damage. The

device is ideal for use in battery powered or power

conscious applications. I_CCis specified at 500 μA

maximum.

–

Permits Live Transceiver

Insertion/Displacement

•

PDIP and SOIC Packages Available

Industrial Temperature Range: −40°C to

+85°C

The driver and receiver outputs feature TRI-STATE

capability. The driver outputs operate over the entire

common mode range of −7V to +12V. Bus contention

or fault situations that cause excessive power

dissipation within the device are handled by a thermal

shutdown circuit, which forces the driver outputs into

the high impedance state.

•

On-Board Thermal Shutdown Circuitry

–

Prevents Damage to the Device in the Event

of Excessive Power Dissipation

•

Wide Common Mode Range: −7V to +12V

(1)

Receiver Open Input Fail-Safe

¼ Unit Load (DS36C278): ≥12 Nodes

½ Unit Load (DS36C278T): ≥64 Nodes

ESD (Human Body Model): ≥2 kV

Drop in Replacement for:

The receiver incorporates a fail safe circuit which

guarantees a high output state when the inputs are

(1)

left open.

The DS36C278T is fully specified over the industrial

LTC485, MAX485, DS75176, DS3695

temperature range (−40°C to +85°C).

(1) Non-terminated, open input only
