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.
