DATASHEET
3.3V Radiation Tolerant CAN Transceiver, 1Mbps, Listen
Mode, Split Termination Output
ISL72027SEH
The Intersil ISL72027SEH is a 3.3V radiation tolerant 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 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 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 ISL72027SEH is available in an 8 Ld hermetic ceramic
flatpack and die form that operate across the temperature
range of the -55°C to +125°C. The logic inputs are tolerant
with 5V systems.
Other CAN transceivers available are the ISL72026SEH and
ISL72028SEH. For a list of differences see Table 1 on page 2.
