DS36276数据手册集成电路（IC）的驱动器接收器收发器规格书PDF

描述 Description

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 (50 Ohm), and SHORTED Inputs.
FAILSAFE is a highly desirable feature when the transceivers are used with Asynchronous Controllers such as UARTs.
