3 Description

The SN65HVD233-Q1, SN65HVD234-Q1, and

SN65HVD235-Q1 devices are fault-protected 3.3-V

CAN transceivers that are qualified for use in

automotive applications. These transceivers work

from a 3.3-V supply and are ideal for systems that

also leverage a 3.3-V microcontroller, thereby

reducing the need for additional components or a

separate supply to power the controller and the CAN

transceiver. The SN65HVD23x-Q1 transceivers are

compatible with the ISO 11898-2 standard and thus

are interoperable in mixed networks that employ 5-V

CAN and/or 3.3-V CAN transceivers.

Designed for operation in especially harsh

environments, the devices feature crosswire

protection, overvoltage protection on the CANH and

CANL pins 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 commonmode

range. These transceivers are the interface

between the host CAN controller on the

microprocessor and the differential CAN bus used in

transportation and automotive applications.
