SN65HVD06中文资料高输出 RS-485 收发器数据手册TI规格书

描述 Description

The SN65HVD05, SN75HVD05, SN65HVD06, SN75HVD06, SN65HVD07, and SN75HVD07 combine a 3-state differential line driver and differential line receiver. Theyare designed for balanced data transmission and interoperate with ANSI TIA/EIA-485-A and ISO 8482E standard-compliant devices. The driver is designedto provide a differential output voltage greater than that required by these standards for increased noise margin. The drivers and receivers have active-highand active-low enables respectively, which can be externally connected together to function as direction control. The driver differential outputs and receiver differential inputs connect internally to form a differential input/ output (I/O) bus port that is designedto offer minimum loading to the bus whenever the driver is disabled or not powered. These devices feature wide positive and negative common-mode voltageranges, making them suitable for party-line applications.
