DS36276 DS36276 FAILSAFE Multipoint Transceiver Literature Number: SNLS085A DS36276
FAILSAFE Multipoint Transceiver
General Description Features The DS36276 FAILSAFE Multipoint Transceiver is designed
for use on bi-directional differential busses. It is compatible
with existing TIA/EIA-485 transceivers, however, it offers an
additional feature not supported by standard transceivers.
The FAILSAFE feature guarantees the receiver output to a
known state when the Interface is in the following conditions:
Floating Line, Idle Line (no active drivers), and Line Fault
conditions (open or short). The receiver output is in a HIGH
state for the following conditions: OPEN Inputs, Terminated
Inputs (50Ω), and SHORTED Inputs.
FAILSAFE is a highly desirable feature when the transceivers are used with Asynchronous Controllers such as UARTs. n FAILSAFE receiver, RO = HIGH for:
— OPEN inputs
— Terminated inputs
— SHORTED inputs
n Compatible with popular interface standards:
— TIA/EIA-485 (RS-485)
— TIA/EIA-422-A (RS-422-A)
— CCITT Recommendation V.11
n Bi-Directional Transceiver
— Designed for multipoint transmissio Separate driver input, driver enable, receiver enable,
and receiver output for maximum flexibility …
