CAN Transceivers

CAN (Controller Area Network) Transceiver ICs are physical-layer interface components designed to bridge the CAN protocol controller with the physical two-wire differential CAN bus cabling. Widely used in automotive electronic control units (ECUs), industrial machinery, and elevator controls, CAN transceivers convert single-ended digital signals from the controller's TXD/RXD pins into high-voltage differential signals on the CANH and CANL bus lines, ensuring highly reliable, noise-immune communication.

Modern systems prioritize CAN FD (Flexible Data-Rate) transceivers which support data rates up to 5 Mbps to handle complex automotive sensor data. Crucial selection specifications include maximum data speed, bus fault protection voltage (often up to +/-58V to survive battery shorts), common-mode voltage range, low-power standby modes with remote wake-up capability, integrated ESD and EMC filtering, and automotive AEC-Q100 qualification. Advanced models feature integrated digital isolation.

Use Octatronics to source high-reliability CAN and CAN FD transceivers from industry giants including NXP Semiconductors (TJA series), Texas Instruments (TCAN series), Infineon Technologies, Microchip Technology, and STMicroelectronics. Filter by package size, data rate, and submit bulk RFQs online.
