SN65HVD1787DR is an integrated circuit designed for physical layer applications, specifically for messaging applications with a lack of high speed requirements. It belongs to the interface - drivers, receivers, transceivers category, which is used in a variety of applications. This integrated circuit is a highly integrated half duplex transceiver, capable of supporting interface communication speeds of up to 200 Kbits per second (Kbps).

The SN65HVD1787DR has two data pins, one transmitting and one receiving. The transmitting data pin, if enabled, will send an output signal from the SN65HVD1787DR module and the receiving pin, if enabled, will allow an external signal to be received by the module. It is capable of working with both asynchronous and synchronous type messaging protocols, with 8N1 (8 piece, no parity and one stop bit) being the most common format.

The SN65HVD1787DR can be used in a variety of applications, including Data Acquisition, Message Sharing, Sensor Control, and Digital Input/Output (DIO). It is a perfect choice when the user needs to support low speed communication among different devices, such as PLCs, RTUs, instruments or control systems. In terms of compatibility, it can operate with different power supply levels and is compliant with several industry standards, including CAN and SAE J1939.

The working principle of SN65HVD1787DR is fairly simple. It uses a voltage-level shifter circuit that runs off a single +5V power source. The voltage shifter receives the messages and passes them through to the 5V logic lines. It then ensures that the transmitted data has the correct voltage levels for the intended receiver. The SN65HVD1787DR has a built-in pull down resistor, which provides reliable electrical connectivity when external power supplies are used. Additionally, power ON/OFF control is provided to enable low-power operation when communication is not required.

In summary, SN65HVD1787DR is an integrated circuit that belongs to the interface - drivers, receivers, transceivers category, offering excellent performance at low cost. It is compatible with a variety of messaging protocols and can be used in many different applications, such as data acquisition, message sharing, sensor control, and digital input/output. Its working principle is based on a voltage-level shifter circuit that runs off a single +5V power source and its power ON/OFF control is provided to enable low-power operation when not required.
