DATASHEET 3.3V Radiation Tolerant CAN Transceiver, with Low Power Shutdown, Split Termination Output ISL72028SEH Features The Intersil ISL72028SEH is a radiation tolerant 3.3V CAN Electrically screened to SMD 5962-15228 transceiver that is compatible with the ISO11898-2 standard for ESD protection on all pins 4kV HBM applications calling for Controller Area Network (CAN) serial Compatible with ISO11898-2 communication in satellites and aerospace communications, and Operating supply range . 3.0V to 3.6V telemetry data processing in harsh industrial environments. Bus pin fault protection to 20V The transceiver can transmit and receive at bus speeds up to 5Mbps. It can drive a 40m cable at 1Mbps per the ISO11898-2 Undervoltage lockout specification. The device is designed to operate over a common- Cold spare: powered down devices/nodes will not affect mode range of -7V to +12V with a maximum of 120 nodes. The active devices operating in parallel device has three discrete selectable driver rise/fall time options, a Three selectable driver rise and fall times low power shutdown mode and a split termination output. Glitch free bus I/O during power-up and power-down Receiver (Rx) inputs feature a full fail-safe design, which ensures a logic high Rx output if the Rx inputs are floating, Full fail-safe (open, short, terminated/undriven) receiver shorted, or terminated but undriven. Hi Z input allows for 120 nodes on the bus The ISL72028SEH is available in an 8 Ld hermetic ceramic High data rates up to 5Mbps flatpack and die form that operate across the temperature range Quiescent supply current 7mA (max) of -55C to +125C. The logic inputs are tolerant with 5V Low power shutdown mode 50A (max) systems. -7V to +12V common-mode input voltage range Other CAN transceivers available are the ISL72026SEH and 5V tolerant logic inputs ISL72027SEH.
