Texas Instruments' SN65HVD230, SN65HVD231, and SN65HVD232 controller area network (CAN) transceivers are compatible to the specifications of the ISO 11898-2 High-Speed CAN Physical Layer standard (transceiver). These devices are designed for data rates up to 1 megabit per second (Mbps) and include many protection features providing device and CAN network robustness. The SN65HVD23x transceivers are designed for use with the Texas Instruments 3.3 V µPs, MCUs, and DSPs with CAN controllers, or with equivalent protocol controller devices. The devices are intended for use in applications employing the CAN serial communication physical layer in accordance with the ISO 11898 standard.

Designed for operation in especially harsh environments, these devices feature cross-wire protection, loss of ground and over-voltage protection, and over-temperature protection, as well as wide common mode range of operation.

The CAN transceiver is the CAN physical layer and interfaces the single-ended host CAN protocol controller with the differential CAN bus found in industrial, building automation, and automotive applications. These devices operate over a -2 V to 7 V common mode range on the bus and can withstand common mode transients of ±25 V.
