            HI-3000H High-Temperature CAN Transceivers
                    Holt Integrated Circuits' HI-3000H is a 1 Mbps Controller Area Network (CAN) transceiver, optimized for use in high-temperature avionics applications
    

Image of Holt Integrated Circuits' HI-3000H High-Temperature CAN Transceivers Holt Integrated Circuits' HI-3000H high-temperature transceiver family is capable of operation up to 200°C in an 8-pin CERDIP package, and up to 175°C in an 8-pin plastic SOIC package.

The devices support two modes of operation: Normal Mode and Standby Mode. The Standby Mode is a very-low-current mode that continues to monitor bus activity, allowing the external controller to manage wake-up. Superior common-mode receiver performance makes the device especially suitable for applications where ground reference voltages may vary from point-to-point over long distances along the CAN bus. In addition, the HI-3000H provides a SPLIT pin to give an output reference voltage of V_DD/2. This can be used for stabilizing the recessive bus level when the split termination technique is used to terminate the bus.

The devices also feature a TXD dominant time-out feature to protect the bus from being driven into a permanent dominant state if the TXD pin becomes permanently low, due to application failure.

The HI-3001H is identical to the HI-3000H, except that the SPLIT pin is substituted with a VIO supply voltage pin. This allows the HI-3001H to interface digital I/O directly with 3.3 V controllers.
