The SN65HVD233 is used in applications employing the controller area network (CAN) serial
communication physical layer in accordance with the ISO 11898 standard, with the exception that the thermal shutdown is removed. As a CAN transceiver, the device provides transmit and receive capability between the differential CAN bus and a CAN controller, with signaling rates up to 1 Mbps.
Designed for operation in especially harsh environments, the device features cross wire, overvoltage, and loss-of-ground protection to ±36 V, with common-mode transient protection of ±100 V. This device operates over a –7-V to 12-V common-mode range with a maximum of 60 nodes on a bus.
