FAILSAFE Multipoint Transceiver
General DescriptionThe DS36276 FAILSAFE Multipoint Transceiveris designed
foruseon bi-directional differential busses.Itis compatible
with existing TIA/EIA-485 transceivers, however,it offersan
additional featurenot supportedby standard transceivers.
The FAILSAFE feature guaranteesthe receiver outputtoa
knownstate whenthe Interfaceisinthe following conditions:
Floating Line, Idle Line(no active drivers),and Line Fault
conditions (openor short). The receiver outputisina HIGH
stateforthe following conditions: OPEN Inputs, Terminated
Inputs (50Ω),and SHORTED Inputs.
FAILSAFEisa highly desirable feature whenthe transceiv-
ersare usedwith Asynchronous Controllers suchas UARTs.
Features FAILSAFE receiver,RO= HIGHfor: OPEN inputs Terminated inputs SHORTED inputs Compatible with popular interface standards: TIA/EIA-485 (RS-485) TIA/EIA-422-A (RS-422-A) CCITT Recommendation V.11 Bi-Directional Transceiver Designedfor multipoint transmission Separate driver input, driver enable, receiver enable,
and receiver outputfor maximum flexibility Widebus common mode range (−7Vto +12V)Pin compatible with: DS75176B, DS96176, DS3695and
