The CA-IF1044x devices are control area network (CAN)  transceivers with integrated protection for industrial and  automotive applications. These devices are designed for  using in CAN FD (flexible data rate) networks up to 5 Mbps  data rate and feature ±58V extended fault protection on  the CAN bus for equipment where overvoltage protection  is required. This family of CAN transceivers also  incorporate an input common-mode range(CMR) of ±30V,  exceeding the ISO 11898 specification of -2V to +7V, well  suited for applications where ground planes from different  systems are shifting relative to each other.

The CA-IF1044x series devices include a dominant timeout  to prevent bus lockup caused by controller error or by a  fault on the TXD input. When the TXD remains in the  dominant state (low) for longer than tDOM, the driver is  switched to the recessive state, releasing the bus and  allowing other nodes to communicate. The transceivers  feature a STB pin for two modes of operation: normal highspeed mode and standby mode for low current  consumption. Also, the CA-IF1044Vx devices in this family  provide low level translation to simplify the interface with  5V, or 3.3V low voltage CAN controllers.
