Pinout
The SN65HVD251DR is a CAN transceiver from Texas Instruments. It is an 8-pin integrated circuit designed for use in Controller Area Network (CAN) bus systems. Here's a brief overview of its pin count and functions:
1. Pin 1 (D): Driver Input - Data input for the CAN driver.
2. Pin 2 (R): Receiver Output - Provides the received data output.
3. Pin 3 (VCC): Supply Voltage - Connects to the power supply (typically 5V).
4. Pin 4 (GND): Ground - Ground reference for the device.
5. Pin 5 (CANH): CAN High - Connects to the high side of the differential CAN bus.
6. Pin 6 (CANL): CAN Low - Connects to the low side of the differential CAN bus.
7. Pin 7 (RS): Slope Control/Standby - Controls the slope of the output signals to reduce EMI; also used for entering standby mode.
8. Pin 8 (NC): No Connect - Typically not connected internally, may be used for mechanical support or PCB routing.
These pins allow the SN65HVD251DR to facilitate communication over a CAN bus by converting between the logic levels of the microcontroller and the differential signals used on the bus.
