The SN65HVD63RGTT is a high speed communication interface device from Texas Instruments which targets automotive applications. It is a low power, bidirectional transceiver that can be used to interface two digital buses. It increases the data rate for two buses and enables communication between microcontrollers, memories, and other digital systems.

The SN65HVD63RGTT can be classified into the category Interface - Drivers, Receivers, Transceivers due to its digital bus transceiver function. It includes two separate independent transceivers with drivers and receivers which can apply to communication between two separate systems.

The SN65HVD63RGTT is well suited for use in automotive applications due to its robust EMI and EMC compliance. Its low power supply voltage and low-power operation make it well-suited for applications with limited energy sources. Additionally, it has fault-tolerant protection which results in reliable performance even in harsh conditions. Its small package size makes it suitable for applications with limited space.

The SN65HVD63RGTT works on the principle of differential signaling. Its transceivers are exceptionally immune to noise and EMI which makes them suitable for CAN and LIN communication systems. It features two driver outputs, two receiver inputs, two direction (VDRIVE) control input signals, and two enable control signals. It has an enable/disable function which selectively enables either the Driver (DTE) or the Receiver (DR) side. The receiver inputs feature filters which help reduce the effects of EMI and noise.

The SN65HVD63RGTT features pseudo open-drain outputs on its receiver side. This feature helps reduce the overall quiescent current and provides a design flexibility. The transceiver also features fail-safe protection. This feature can be activated or deactivated by external control which allows the receiver side to interpret a low-level logical 0 state while the bus line is uncontrolled or floating.

The SN65HVD63RGTT is also equipped with built-in thermal protection circuitry. This helps protect the device against sudden current spikes which can cause permanent damage. Its integrated protection circuits detect a high temperature condition and will shut down the device until the temperature drops to a safe level.

Overall, the SN65HVD63RGTT provides a reliable solution for automotive applications which require high speed communication between two digital buses. It features low-power operation, robust fault-tolerant protection, and pseudo open-drain outputs. Its enable/disable control selectively enables either the driver (DTE) or receiver (DR) side and helps reduce the overall quiescent current. Additionally, the integrated thermal protection circuitry helps protect the device from current spikes.
