Rev 3.00
August 16, 2016 3.3V Radiation Tolerant CAN Transceiver, with Low Power Shutdown, Split
Termination Output
The Intersil ISL72028SEH 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. Features The transceiver can transmit and receive at bus speeds up to
5Mbps. It can drive a 40m cable at 1Mbps per the ISO11898-2
specification. The device is designed to operate over a commonmode range of -7V to +12V with a maximum of 120 nodes. The
device has three discrete selectable driver rise/fall time options, a
low power shutdown mode and a split termination output. Operating supply range . 3.0V to 3.6V 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. Three selectable driver rise and fall times The ISL72028SEH is available in an 8 Ld hermetic ceramic
flatpack and die form that operate across the temperature range
of -55В°C to +125В°C. The logic inputs are tolerant with 5V
systems. Electrically screened to SMD 5962-15228 ESD protection on all pins 4kV HBM Compatible with ISO11898-2 Bus pin fault protection to В±20V Undervoltage lockout Cold spare: powered down devices/nodes will not affect
active devices operating in parallel Glitch free bus I/O during power-up and power-down Full fail-safe (open, short, terminated/undriven) receiver Hi Z input allows for 120 nodes on the bus High data rates up to 5Mbps Quiescent supply current 7mA (max) Other CAN transceivers available are the ISL72026SEH and
ISL72027SEH. For a list of differences see Table 1 on page 2.
