DS36C279

Low Power EIA-RS-485 Transceiver with Sleep Mode

General Description

Features

n 100% RS-485 compliant

The DS36C279 is a low power differential bus/line trans-

ceiver designed to meet the requirements of RS-485 Stan-

dard for multipoint data transmission. In addition it is compat-

ible with TIA/EIA-422-B.

— Guaranteed RS-485 device interoperation

n Low power CMOS design: I_CC500 µA max

n Automatic sensing sleep mode

— Reduces I_CCto 10 µA maximum

n Built-in power up/down glitch-free circuitry

The sleep mode feature automatically puts the device in a

power saving mode when both the driver and receiver are

††

disabled. The device is ideal for use in power conscious

— Permits live transceiver intersection/displacement

n DIP and SOIC packages available

n Industrial temperature range: −40˚C to +85˚C

n On-board thermal shutdown circuitry

— Prevents damage to the device in the event of

excessive power dissipation

n Wide common mode range: −7V to +12V

applications where the device may be disabled for extended

periods of time.

The driver and receiver outputs feature TRI-STATE^®capabil-

ity. 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.

n Receive open input fail-safe (Note 1)

⁄

unit load (DS36C279): ≥ 128 nodes

unit load (DS36C279T): ≥ 64 nodes

The receiver incorporates a fail safe circuit which guarantees

a high output state when the inputs are left open.

†

n ESD (Human Body Model): ≥ 2 kV

n Drop-in replacement for:

— LTC485 MAX485 DS75176 DS3695

The DS36C279T is fully specified over the industrial tem-

perature range (−40˚C to +85˚C).
