Dominant Mode Multipoint Transceiver
DS36277
Dominant Mode Multipoint Transceiver
General Description

The DS36277 Dominant Mode Multipoint Transceiveris de-
signedfor useon bi-directional differential busses.Itis opti-
malfor useon Interfaces that utilize Societyof Automotive
Engineers (SAE) J1708 Electrical Standard.
The deviceis similarto standard TIA/EIA-485 transceivers,
but differsin enabling scheme. The Driver’s Inputis normally
externally tied LOW, thus providing only two states: Active
(LOW),or Disabled (OFF). When the driveris active, the
dominant modeis LOW, conversely, whenthe driveris dis-
abled,the busis pulled HIGHby external bias resistors.
The receiver providesa FAILSAFE feature that guaranteesa
known output state when the Interfaceisin the following
conditions: Floating Line, Idle Line (no active drivers), and
Line Fault Conditions (openor short). The receiver outputis
HIGHforthe following conditions: Open Inputs, Terminated
Inputs (50Ω),or Shorted Inputs. FAILSAFEisa highly desir-
able feature when the transceivers are used with Asynchro-
nous Controllers suchas UARTs.
