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, overvoltage and loss of
ground protection to ±36 V, with overtemperature
protection and common-mode transient protection of
±100 V. These devices operate over a –7-V to 12-V
common-mode range with a maximum of 60 nodes on a
bus.
