DescriptionThe 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 DS36276 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 (50?), and SHORTED Inputs.
DS36276 FAILSAFE is a highly desirable feature when the transceiv-ers are used withAsynchronous Controllers such as UARTs.
