3 Description

The SN55HVD233-SEP is used in applications

employing the controller area network (CAN) serial

communication physical layer in accordance with the

ISO 11898 standard. 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 radiation

environments, the SN55HVD233-SEP features crosswire,

overvoltage, loss of ground protection to ±16 V,

and overtemperature (thermal shutdown) protection.

This device operates over a wide –7-V to 12-V

common mode range. This transceiver is the interface

between the host CAN controller on the

microprocessor, FPGA, or ASIC, and the differential

CAN bus used in satellite applications.
