3 Description

The SN65HVD233, SN65HVD234, and SN65HVD235

are used in applications employing the controller area

network (CAN) serial communication physical layer in

accordance with the ISO 11898 standard. As a CAN

transceiver, each 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 devices feature cross-wire

protection, overvoltage protection up to ±36 V, loss of

ground protection, overtemperature (thermal

shutdown) protection, and common-mode transient

protection of ±100 V. These devices operate over a

wide –7 V to 12 V common-mode range. These

transceivers are the interface between the host CAN

controller on the microprocessor and the differential

CAN bus used in industrial, building automation,

transportation, and automotive applications.
