3.3V Radiation Tolerant CAN Transceiver, with Low
Power Shutdown, Split Termination Output
ISL72028SEH
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.
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 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
low power shutdown mode and a split termination output.
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.
The ISL72028SEH 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.
Other CAN transceivers available are the ISL72026SEH and
ISL72027SEH. For a list of differences see Table 1 on page 2.
