The SN65HVD232QDR is an advanced 3-line differential bus transceiver specifically designed to operate over a prolonged temperature range from -40°C to 85°C. It is based on the advanced half-duplex, low-power transceiver architecture, which combines integrated low-voltage differential signaling (LVDS) line driver and receiver with integrated termination resistors and fast active, high-impedance fail-safe receiver. It is typically used for communication applications in industrial, consumer and automotive applications as well as for linking high-speed data-acquisition systems with field buses.

The SN65HVD232QDR transceiver is typically used in two-wire bus systems such as CAN, LIN, and Ethernet. It is used in conjunction with a digital supplier, such as a microcontroller, to provide full-duplex, bidirectional communication between devices in these networks. The SN65HVD232QDR contains two driver and two receiver channels with logic-level translator functionality that can operate up to a maximum of 1 Mbit/s.

The primary application field of the SN65HVD232QDR transceiver is data communications over high-speed and long-distance bus systems such as CAN, LIN and Ethernet. Its other applications include controlling high-speed, high-accuracy servos, motor drives, and sensors, as well as transmitting and receiving data from programmable controllers and robotics.

The working principle of the SN65HVD232QDR is based on its integrated low-voltage differential signaling (LVDS) line driver and receiver, which is designed for high-impedance loops and long transmission distances operating in an extended temperature range from -40°C to 125°C. The LVDS line driver generates differential signals that protect the transmitted data against common-mode noise, EMC tests, and other environmental disturbances. The receivers also contain fast active, high-impedance fail-safe circuitry, which ensures proper data reception even in noisy or low-voltage signal conditions.

The SN65HVD232QDR transceiver contains two driver and two receiver channels with logic-level translator functionality that can operate up to a maximum of 1 Mbit/s. Its integrated termination resistors provide uniform signal termination both at the driver and receiver nodes, while its slew rate acceleration and line impedance stabilization techniques (LIS) reduce signal reflections and crosstalk between channels to ensure reliable data transmission.

The SN65HVD232QDR transceiver is designed for a wide variety of data communications applications, including industrial, consumer, and automotive markets. Its high-speed, low-power, and reliable operation make it ideal for high-speed, long-distance systems such as CAN, LIN and Ethernet, as well as for controlling high-speed, high-accuracy servos, motor drives, and sensors.
