The SN65HVD71DGKR is a widely used transfer-oriented interface chip. It is a driver, receiver, transceiver and enables communication in full-duplex or half duplex between two devices. An integrated bidirectional level translator allows for using the chip with an integrated data link layer and directly connecting two 5V or a 5V and a 3V system. The SN65HVD71DGKR also provides up to ± 15 kV ESD protection. With its pin saving and low power consumption, this chip is suitable for applications in automotive, industrial, and medical systems as well as other modern industrial communication applications.

The SN65HVD71DGKR has a 7-pin configuration and is designed for integrated 5V or 3V operation. It features two transceivers that operate in both transmit and receive directions and provide full duplex or half duplex communication. A set of shift register is built into the chip to allow for two-directional data transfer. The integrated bidirectional logic level translators allow signals from different voltage systems to be exchanged without any conversion. The chip also includes an internal ESD protection circuit to protect against electrostatic damage.

The SN65HVD71DGKR has an easy to use interface. It uses an SPI-compatible serial data format with up to 40-bit frame size. It also supports up to 350 kbps communications speeds. The chip offers an adjustable threshold of current-limit Input/Output buffers, enabling users to fine-tune its input/output buffering and signal isolation parameters. Its low power consumption and small form factor make it suitable for a wide range of industrial and automotive applications.

The working principle of SN65HVD71DGKR is that when one of the two devices sends data, the transceiver on the SN65HVD71DGKR chip receives it and converts it into logic level signals. This signal is then transmitted to the receiver as an output signal. The receiver then transfers the data to the destination system. The direction of the data flow can be reversed, allowing for a full-duplex communication between two devices. The level translator on the SN65HVD71DGKR chip then consists of a combination of current limiters, which can be adjusted, to ensure that the signals are completely isolated and the data is transmitted in its original form.

The SN65HVD71DGKR is suitable for many industrial communication applications. It is used in automotive systems, in industrial automation applications such as PLCs, in medical systems, and in consumer electronics such as smart TVs. It is ideal for applications where a compact form factor, low power consumption and reliable data transmission are required. The built-in robust ESD protection circuit ensures that the SN65HVD71DGKR is reliable and can withstand extreme conditions.

In conclusion, the SN65HVD71DGKR is an industrial interface chip that is excellent choice for communication needs. It is suitable for automotive and industrial systems, as well as consumer electronics and medical applications. The chip has low power consumption and a small form factor, and provides reliable data transmission with up to ± 15 kV ESD protection. The integrated logic level translator and bidirectional data link layer allows the signals from different voltage systems to be exchanged without any conversion.
