Controller Area Network (CAN)

Holt’s CAN network IC products integrate seamlessly with higher layer industrial protocols such as CAN open or DeviceNet. The HI-3110 with SPI host interface was the first CAN product to integrate the transceiver on the same chip as the controller, ensuring a highly compact single-chip solution. Holt also offers standalone transceiver and CAN controller ICs. Select transceiver products are capable of very high operating temperatures (up to 200oC).
