3 Description
The SN55HVD233-SP is used in spacecraft
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-SP features crosswire,
overvoltage, and loss of ground protection to
±16 V, 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.
