3 Description
The SN65HVD233 is used in applications employing
the controller area network (CAN) serial communication physical layer in accordance with the
ISO 11898 standard, with the exception that the
thermal shutdown is removed. As a CAN transceiver,
the device 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 device features cross wire,
overvoltage, and loss-of-ground protection to ±36 V,
with common-mode transient protection of ±100 V.
This device operates over a –7-V to 12-V common•
mode range with a maximum of 60 nodes on a bus.
If the common-mode range is restricted to the ISO
11898 standard range of –2 V to 7 V, up to 120
nodes may be connected on a bus. This transceiver
interfaces the single-ended CAN controller with the
differential CAN bus found in industrial, building
automation, and automotive applications.
