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.
