Pin Functions for SN65HVD12DR (SOIC-8 package)
Pin Count: 8 Pins
Pin Number Pin Name Pin Function Description 1 CANH CAN High: This is the CAN bus high signal. It carries the differential signal for CAN communication. It is used to communicate with other CAN bus devices. 2 CANL CAN Low: This is the CAN bus low signal. It works together with CANH to form a differential pair that carries the data across the bus. 3 VCC Supply Voltage: This pin supplies power to the transceiver. Typically, it is powered with a voltage between 4.5V and 5.5V to ensure proper operation. 4 GND Ground: This pin is the ground connection for the IC. It connects to the common ground of the system. 5 TXD Transmit Data: This is the input for the data transmission. It receives a logic level signal from a controller or microprocessor and drives the CAN bus. 6 RXD Receive Data: This is the output for received data. It sends a logic level signal that corresponds to the data received over the CAN bus. 7 RE Receive Enable: This pin controls whether the receiver is enabled. When high, the receiver is enabled and can accept CAN messages. When low, the receiver is disabled. 8 STB Standby: This pin is used to put the transceiver in standby mode. It is typically a low-power mode when the system is not actively using the CAN bus.Detailed FAQs for SN65HVD12DR
