SN65HVD1471DGKR

The SN65HVD1471DGKR is a quad differential driver from Texas Instruments. It is used to drive data buses in applications such as LIN and CAN bus systems, point-to-point data links, various bus communication systems, and many other automotive, industrial, and consumer applications. The SN65HVD1471DGKR is able to provide an output current of up to 300 mA and is capable of operation in both single-ended or differential signaling mode, making it a great choice for applications that require both robustness and flexibility.

Working Principle

The SN65HVD1471DGKR is a differential driver. It consists of four independent transmitters that can convert a single-ended input signal into a true differential output signal. This allows for better noise rejection without needing to increase the impedance of the signal line. The SN65HVD1471DGKR features open circuit and short circuit protection for both input and output pins and provides improved electromagnetic interference (EMI) results in comparison with single-ended IO devices.

Each driver inside the SN65HVD1471DGKR has two inputs, DEN and /DEN, that control the output states. When DEN is asserted high, the output will be driven with the complementary input signals. When the DEN input is low, the outputs are placed in a high impedance state, ready to be driven with the next signal. The SN65HVD1471DGKR also has a fault signal output (/FOUT) that indicates if any of the drivers has been disabled due to an excessive output current or an overtemperature condition.

The SN65HVD1471DGKR has a wide common mode range of -2V to +7V which allows the outputs to be driven to either rail. The number of possible output scenarios for the SN65HVD1471DGKR is almost unlimited making this device suitable for a variety of applications.

Applications

The SN65HVD1471DGKR is a great choice for applications that require both robustness and flexibility. It is suitable for use in a variety of bus communication systems including CAN bus systems, LIN bus systems, and point-to-point data links.
