DS36C279 Low Power EIA-RS-485 Transceiver with Sleep Mode

Check for Samples: DS36C279

FEATURES

DESCRIPTION

The DS36C279 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

Specified RS-485 Device Interoperation

–

•

Low Power CMOS Design: I_CC500 μA Max

Automatic Sensing Sleep Mode

The sleep mode feature automatically puts the device

in a power saving mode when both the driver and

receiver are disabled.⁽²⁾The device is ideal for use in

power conscious applications where the device may

be disabled for extended periods of time.

–

Reduces I_CCto 10 μA Maximum

•

Built-in Power Up/Down Glitch-Free Circuitry

–

Permits Live Transceiver

Intersection/Displacement

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

a high impedance state.

•

SOIC Packages

Industrial Temperature Range: −40°C to

+85°C

•

On-Board Thermal Shutdown Circuitry

–

Prevents Damage to the Device in the Event

of Excessive Power Dissipation

The receiver incorporates a fail safe circuit which

ensures a high output state when the inputs are left

open.⁽³⁾

•

Wide Common Mode Range: −7V to +12V

Receive Open Input Fail-Safe⁽¹⁾

¼ Unit Load (DS36C279): ≥ 128 Nodes

½ Unit Load (DS36C279T): ≥ 64 Nodes

ESD (Human Body Model): ≥ 2 kV

Drop-In Replacement for:

The DS36C279T is fully specified over the industrial

temperature range (−40°C to +85°C).

(2) Device enters sleep mode if enable conditions are held > 600
