DATASHEET 3.3V Radiation Tolerant CAN Transceiver, 1Mbps, Listen Mode, Loopback ISL72026SEH Features The Intersil ISL72026SEH is a radiation tolerant 3.3V CAN transceiver that is compatible with the ISO11898-2 standard for applications calling for Controller Area Network (CAN) serial communication in satellites and aerospace communications and telemetry data processing in harsh industrial environments. • Electrically screened to SMD 5962-15228 The transceiver can transmit and receive at bus speeds of up to 1Mbps. The device is designed to operate over a common mode range of -7V to +12V with a maximum of 120 nodes. The device has three discrete selectable driver rise/fall time options, a listen mode feature and loopback test capability. • Undervoltage lockout Receiver (Rx) inputs feature a “full fail-safe” design, which ensures a logic high Rx output if the Rx inputs are floating, shorted, or terminated but undriven. • Glitch free bus I/O during power-up and power-down The ISL72026SEH is available in an 8 Ld hermetic ceramic flatpack and die form that operate across the temperature range of -55°C to +125°C. The logic inputs are tolerant with 5V systems. • High data rates. . . . . . . . . . . . . . . . . . . . . . . . . . . up to 1Mbps Other CAN transceivers available are the ISL72027SEH and ISL72028SEH.

OUTPUT SHORT CIRCUIT CURRENT TEST CIRCUIT -7V FIGURE 19B. OUTPUT SHORT CIRCUIT CURRENT WAVEFORMS FIGURE 19. OUTPUT SHORT CIRCUIT CURRENT Functional Description Overview The Intersil ISL72026SEH is a 3.3V radiation tolerant CAN transceiver that is compatible with the ISO11898-2 standard for use in CAN (Controller Area Network) serial communication systems. The device performs transmit and receive functions between the CAN controller and the CAN differential bus. It can transmit and receive at bus speeds of up to 1Mbps. It is designed to operate over a common mode range of -7V to +12V with a maximum of 120 nodes. The device is capable of withstanding ±20V on the CANH and CANL bus pins outside of ion beam and ±16V under ion beam. Slope Adjustment The output driver rise and fall time has three distinct selections that may be chosen by using a resistor from the RS pin to GND. Connecting the RS pin directly to GND results in output switching times that are the fastest, limited only by the drive capability of the output stage. RS = 10kΩ provides for a typical slew rate of 8V/µs and RS = 50kΩ provides for a typical slew rate of 4V/µs. Putting a high logic level to the RS pin places the device in a low current listen mode. The protocol controller uses this mode to switch between low power listen mode and normal transmit mode. Cable Length The device can work per ISO11898 specification with a 40m cable and stub length of 0.3m and 60 nodes at 1Mbps. This is greater than the ISO requirement of 30 nodes. The cable type specified is twisted pair (shielded or unshielded) with a characteristic impedance of 120Ω. Resistors equal to this are to be terminated at both ends of the cable. Stubs should be kept as short as possible to prevent reflections. Submit Document Feedback 10 Cold Spare High reliability system designers implementing data communications have to be sensitive to the potential for single point failures. To mitigate the risk of a failure they will use redundant bus transceivers in parallel. In this arrangement both active and quiescent devices can be present simultaneously on the bus. The quiescent devices are powered down for cold spare and do not affect the communication of the other active nodes. To achieve this, a powered down transceiver (VCC < 200mV) has a resistance between the CANH or CANL bus pin and the VCC supply rail of > 480kΩ (max) with a typical resistance > 2MΩ. The resistance between CANH and CANL of a powered-down transceiver has a typical resistance of 80kΩ. Listen Mode When a high level is applied to the RS pin, the device enters a low power listen mode. The driver of the transceiver is switched off to conserve power while the receiver remains active. In listen mode the transceiver draws 2mA (max) of current. A low level on the RS pin brings the device back to normal operation. Loopback Mode When a high level is applied to the LBK pin, the device enters the loopback state. The transceiver CANH and CANL pins are disconnected from the bus. The driver and receiver circuitry of the transceiver remains active to allow for diagnostic testing of the node. Using 3.3V Devices in 5V Systems Looking at the differential voltage of both the 3.3V and 5V devices, the differential voltage is the same, the recessive common mode output is the same. The dominant common mode output voltage is slightly lower than the 5V counterparts. The receiver specs are also the same. Though the electrical parameters appear compatible it is advised that necessary system testing be performed to verify interchangeable operation.
