SN65HVD61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 SN65HVD61 is designed to meet the requirements for the driver and receiver circuitry of the ControlNet coaxial-based physical layer. These devices are single-channel circuits with one transceiver for single node operation or distributed stand-alone applications. The pull-or-pull transmitter circuit is designed to sink current from a center-tapped transformer, providing galvanic isolation from the shared bus. These devices incorporate a differential receiver (RX) with the 120 mV sensitivity needed by ControlNet industrial applications. A secondary receiver (CD) detects the presence of a valid positive differential signal. The third signal receiver function (SIG) provides a scaled analog output which is proportional to the differential voltage between XF1 and XF3. This output can be used for diagnostic purposes.
