DATASHEET
3.3V Radiation Tolerant CAN Transceiver, with Listen
Mode and 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 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 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.
