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.
