The SN65HVD22D is a 3.3V CAN (Controller Area Network) transceiver from Texas Instruments. It comes in an 8-pin SOIC (Small Outline Integrated Circuit) package. Below is a brief description of its pin functions:
1. Pin 1 (D): Driver input. This is where you send data to be transmitted on the CAN bus.
2. Pin 2 (GND): Ground. This is the reference ground for the transceiver.
3. Pin 3 (VCC): Power supply input. It requires a 3.3V power supply.
4. Pin 4 (R): Receiver output. This pin outputs the received data from the CAN bus.
5. Pin 5 (CANH): High-level CAN bus line. Works with CANL to transmit differential signals.
6. Pin 6 (CANL): Low-level CAN bus line. It complements CANH for differential signaling.
7. Pin 7 (Rs): Slope resistance. Used to control the rise and fall times of the CAN bus signals.
8. Pin 8 (NC): No connection. This pin is not internally connected.
This transceiver is designed for high-speed CAN applications and provides differential signaling for robust data communication.
